The concentration of dust, for application of respirable dust limits, is to be determined from thefraction that penetrates a separator whose size collection efficiency is described by a cumulative log-normalfunction with a median aerodynamic diameter of 4.0 µm (+-) 0.3 µm and with a geometric standard deviation of1.5 µm (+-) 0.1 µm, i.e..generally less than 5 µm.

PERSONAL PROTECTION

EYE• Safety glasses with side shields.• Chemical goggles.• Contact lenses may pose a special hazard; soft contact lenses may absorb and concentrate irritants. A

written policy document, describing the wearing of lens or restrictions on use, should be created for eachworkplace or task. This should include a review of lens absorption and adsorption for the class ofchemicals in use and an account of injury experience. Medical and first-aid personnel should be trained intheir removal and suitable equipment should be readily available. In the event of chemical exposure, begineye irrigation immediately and remove contact lens as soon as practicable. Lens should be removed at thefirst signs of eye redness or irritation - lens should be removed in a clean environment only after workershave washed hands thoroughly.

ENGINEERING CONTROLS■ Engineering controls are used to remove a hazard or place a barrier between the worker and the hazard. Well-designed engineering controls can be highly effective in protecting workers and will typically be independentof worker interactions to provide this high level of protection.The basic types of engineering controls are:Process controls which involve changing the way a job activity or process is done to reduce the risk.Enclosure and/or isolation of emission source which keeps a selected hazard "physically" away from the workerand ventilation that strategically "adds" and "removes" air in the work environment. Ventilation can removeor dilute an air contaminant if designed properly. The design of a ventilation system must match theparticular process and chemical or contaminant in use.Employers may need to use multiple types of controls to prevent employee overexposure.

General exhaust is adequate under normal operating conditions. Local exhaust ventilation may be required inspecific circumstances. If risk of overexposure exists, wear approved respirator. Correct fit is essential toobtain adequate protection. Provide adequate ventilation in warehouse or closed storage areas. Aircontaminants generated in the workplace possess varying "escape" velocities which, in turn, determine the"capture velocities" of fresh circulating air required to effectively remove the contaminant.

Type of Contaminant: Air Speed:solvent, vapours, degreasing etc., evaporating 0.25- 0.5 m/s (50- 100 f/min)from tank (in still air).aerosols, fumes from pouring operations, 0.5- 1 m/s (100- 200 f/min.)intermittent container filling, low speedconveyer transfers, welding, spray drift,plating acid fumes, pickling (released at lowvelocity into zone of active generation)direct spray, spray painting in shallow booths, 1- 2.5 m/s (200- 500 f/min.)drum filling, conveyer loading, crusher dusts,gas discharge (active generation into zone ofrapid air motion)

continued...




grinding, abrasive blasting, tumbling, high 2.5- 10 m/s (500- 2000 f/min.)speed wheel generated dusts (released at highinitial velocity into zone of very high rapidair motion).

Within each range the appropriate value depends on:

Lower end of the range Upper end of the range1: Room air currents minimal or favourable to 1: Disturbing room air currentscapture2: Contaminants of low toxicity or of nuisance 2: Contaminants of high toxicityvalue only.3: Intermittent, low production. 3: High production, heavy use4: Large hood or large air mass in motion 4: Small hood- local control only

Simple theory shows that air velocity falls rapidly with distance away from the opening of a simpleextraction pipe. Velocity generally decreases with the square of distance from the extraction point (insimple cases). Therefore the air speed at the extraction point should be adjusted, accordingly, afterreference to distance from the contaminating source. The air velocity at the extraction fan, for example,should be a minimum of 1-2 m/s (200-400 f/min) for extraction of solvents generated in a tank 2 metersdistant from the extraction point. Other mechanical considerations, producing performance deficits within theextraction apparatus, make it essential that theoretical air velocities are multiplied by factors of 10 ormore when extraction systems are installed or used.

POTENTIAL HEALTH EFFECTS

ACUTE HEALTH EFFECTS

SWALLOWED■ The material has NOT been classified by EC Directives or other classification systems as "harmful byingestion". This is because of the lack of corroborating animal or human evidence. The material may still bedamaging to the health of the individual, following ingestion, especially where pre-existing organ (eg. liver,kidney) damage is evident. Present definitions of harmful or toxic substances are generally based on dosesproducing mortality rather than those producing morbidity (disease, ill-health). Gastrointestinal tractdiscomfort may produce nausea and vomiting. In an occupational setting however, ingestion of insignificantquantities is not thought to be cause for concern.

EYE■ There is some evidence to suggest that this material can cause eye irritation and damage in some persons.

SKIN■ The material is not thought to produce adverse health effects or skin irritation following contact (asclassified by EC Directives using animal models). Nevertheless, good hygiene practice requires that exposurebe kept to a minimum and that suitable gloves be used in an occupational setting.Entry into the blood-stream, through, for example, cuts, abrasions or lesions, may produce systemic injurywith harmful effects. Examine the skin prior to the use of the material and ensure that any external damageis suitably protected.

INHALED■ Inhalation hazard is increased at higher temperatures.The material is not thought to produce adverse health effects or irritation of the respiratory tract (asclassified by EC Directives using animal models). Nevertheless, good hygiene practice requires that exposurebe kept to a minimum and that suitable control measures be used in an occupational setting.Not normally a hazard due to non-volatile nature of product.Inhalation of oil droplets or aerosols may cause discomfort and may produce chemical inflammation of thelungs.

CHRONIC HEALTH EFFECTS■ Substance accumulation, in the human body, may occur and may cause some concern following repeated or long-term occupational exposure.There is ample evidence that this material can be regarded as being able to cause cancer in humans based onexperiments and other information.Oil may contact the skin or be inhaled. Extended exposure can lead to eczema, inflammation of hair follicles,pigmentation of the face and warts on the soles of the feet. Exposure to oil mists can cause asthma,pneumonia and scarring of the lungs. Oils have been linked to cancer of the skin and scrotum. Compounds thatare less viscous and with smaller molecular weights are more dangerous. There may be liver damage and the

lymph nodes may be affected; heart inflammation can also occur at high doses.High boiling residues of petroleum process can produce both benign and malignant skin tumours, according toanimal testing. They may contain significant concentrations of polynuclear aromatic hydrocarbons (PAHs).Overexposure to respirable dust may cause coughing, wheezing, difficulty in breathing and impaired lungfunction. Chronic symptoms may include decreased vital lung capacity, chest infectionsRepeated exposures, in an occupational setting, to high levels of fine- divided dusts may produce a conditionknown as pneumoconiosis which is the lodgement of any inhaled dusts in the lung irrespective of the effect.This is particularly true when a significant number of particles less than 0.5 microns (1/50,000 inch), arepresent. Lung shadows are seen in the X-ray. Symptoms of pneumoconiosis may include a progressive dry cough,shortness of breath on exertion (exertional dyspnea), increased chest expansion, weakness and weight loss. Asthe disease progresses the cough produces a stringy mucous, vital capacity decreases further and shortness ofbreath becomes more severe. Other signs or symptoms include altered breath sounds, diminished lung capacity,diminished oxygen uptake during exercise, emphysema and pneumothorax (air in lung cavity) as a rarecomplication.Removing workers from possibility of further exposure to dust generally leads to halting the progress of thelung abnormalities. Where worker-exposure potential is high, periodic examinations with emphasis on lungdysfunctions should be undertakenDust inhalation over an extended number of years may produce pneumoconiosis.. Pneumoconiosis is theaccumulation of dusts in the lungs and the tissue reaction in its presence. It is further classified as beingof noncollagenous or collagenous types. Noncollagenous pneumoconiosis, the benign form, is identified byminimal stromal reaction, consists mainly of reticulin fibres, an intact alveolar architecture and ispotentially reversible.

RESIDUAL OILS, PETROLEUM, SOLVENT-DEWAXED:■ The materials included in the Lubricating Base Oils category are related from both process and physical-chemical perspectives;The potential toxicity of a specific distillate base oil is inversely related to the severity or extent ofprocessing the oil has undergone, since:• The adverse effects of these materials are associated with undesirable components, and• The levels of the undesirable components are inversely related to the degree of processing;• Distillate base oils receiving the same degree or extent of processing will have similar toxicities;• The potential toxicity of residual base oils is independent of the degree of processing the oil receives.• The reproductive and developmental toxicity of the distillate base oils is inversely related to the degree

of processing.Unrefined & mildly refined distillate base oils contain the highest levels of undesirable components, havethe largest variation of hydrocarbon molecules and have shown the highest potential carcinogenic andmutagenic activities. Highly and severely refined distillate base oils are produced from unrefined and mildlyrefined oils by removing or transforming undesirable components. In comparison to unrefined and mildlyrefined base oils, the highly and severely refined distillate base oils have a smaller range of hydrocarbonmolecules and have demonstrated very low mammalian toxicity. Mutagenicity and carcinogenicity testing ofresidual oils has been negative, supporting the belief that these materials lack biologically activecomponents or the components are largely non-bioavailable due to their molecular size.

Toxicity testing has consistently shown that lubricating base oils have low acute toxicities. Numerous testshave shown that a lubricating base oil’s mutagenic and carcinogenic potential correlates with its 3-7 ring

polycyclic aromatic compound (PAC) content, and the level of DMSO extractables (e.g. IP346 assay), bothcharacteristics that are directly related to the degree/conditions of processing.Residual Base OilsResidual oils have substantial polycyclic aromatic compound (PAC) levels when assayed by traditional methods.On this basis, they would be expected to have mutagenic and/or carcinogenic activity. However, no adverseeffects have been seen in either in vitro mutagenicity or dermal carcinogenicity testing of residual baseoils, irrespective of the degree of processing they have undergone. Ultraviolet, HPLC/UV, GC/MS, and infraredanalyses of these oils indicate that the aromatics they contain are predominantly 1-3 rings that are highlyalkylated (paraffinic and naphthenic). Because they are found in such a high boiling material (> 550 C), itis estimated that the alkyl side-chains of these 1-3 ring aromatics would be approximately 13 to 25 carbonsin length. These highly alkylated aromatic ring materials are either devoid of the biological activitynecessary to cause mutagenesis and carcinogenesis, or are largely non-bioavailable to the organismsAcute toxicity: There are no acute toxicity data available for the residual base oils. It is thought that thehigh molecular weight of these materials and associated low bioavailability preclude the systemic dosesnecessary to produce acute toxicity. Furthermore, tests of a variety of distillate base oils, includingunrefined materials that contain high levels of biologically active materials, have consistently shown lowacute toxicity.Repeat dose toxicity: No subchronic repeat-dose studies have been reported on residual base oils. However,two dermal carcinogenicity studies have been performedReproductive and developmental toxicity: There are no reproductive or developmental toxicity data availablefor the residual base oilsCarcinogenicity: A dermal carcinogenicity study of a residual base oil in mice has been reported. The testsubstance was described as “a non-solvent refined, deasphalted, dewaxed residual paraffinic lubricant baseoil". For eighteen months, three times/week, undiluted test material was applied to the skin of female CF1mice. Two other groups of mice underwent similar treatments, but for only 22 or 52 weeks. The base oilproduced minimal clinical evidence of skin irritation. No tumours of epidermal origin were observed inanimals dosed with the base oil. Furthermore, no treatment-related effects were observed with regard toclinical condition, body weight gain, mortality or post mortem findings.A second dermal carcinogenicity study of a residual base oil has been conducted in male C3H/HeJ mice. Thetest substance was described as “deasphalted, dewaxed, residual oil”. The test material was applied undilutedto the animals’ backs, three times/week for 24 months. None of the animals treated with the test materialdeveloped skin tumours, or any other tumours considered treatment-related.The absence of systemic toxicity in these two dermal carcinogenicity studies supports the belief that thehigh molecular weight of the residual base oils and the resulting low bioavailability preclude the internaldoses necessary to elicit systemic toxicity.Genotoxicity:In vitro (mutagenicity): Samples of a vacuum residuum and four residual base oils tested negative for theinduction of frame shift mutations in modified Ames assaysIn vivo (chromosomal aberrations): There is no in vivo genotoxicity data available for the residual baseoils. However, in vitro mutagenicity tests have been conducted on residual base oils and have producednegative results. Dermal carcinogenicity studies on these materials have also been negative. Given theseconsistent results, and the low bioavailability of these materials, it is expected that in vivo mutagenicitytests would also be negative.

BENTONITE:TOXICITY IRRITATIONIntravenous (Rat) LD50: 35 mg/kgIntravenous (Dog) LD: 10 mg/kg■ Asthma-like symptoms may continue for months or even years after exposure to the material ceases. This maybe due to a non-allergenic condition known as reactive airways dysfunction syndrome (RADS) which can occurfollowing exposure to high levels of highly irritating compound. Key criteria for the diagnosis of RADSinclude the absence of preceding respiratory disease, in a non-atopic individual, with abrupt onset ofpersistent asthma-like symptoms within minutes to hours of a documented exposure to the irritant. Areversible airflow pattern, on spirometry, with the presence of moderate to severe bronchial hyperreactivity

continued...




on methacholine challenge testing and the lack of minimal lymphocytic inflammation, without eosinophilia,have also been included in the criteria for diagnosis of RADS. RADS (or asthma) following an irritatinginhalation is an infrequent disorder with rates related to the concentration of and duration of exposure tothe irritating substance. Industrial bronchitis, on the other hand, is a disorder that occurs as result ofexposure due to high concentrations of irritating substance (often particulate in nature) and is completelyreversible after exposure ceases. The disorder is characterised by dyspnea, cough and mucus production.for bentonite clays:Bentonite (CAS No. 1302-78-9) consists of a group of clays formed by crystallisation of vitreous volcanicashes that were deposited in water.The expected acute oral toxicity of bentonite in humans is very low (LD50>15 g/kg). However, severe anteriorsegment inflammation, uveitis and retrocorneal abscess from eye exposure were reported when bentonite hadbeen used as a prophypaste.In a 33 day dietary (2 and 6%) and a 90 day dietary (1, 3 and 5%) studies in chickens, no changes inbehaviour, overall state, clinical and biochemical parameters and electrolytic composition of the blood.Repeat dietary administration of bentonite did not affect calcium or phosphorus metabolism. However, largeramounts caused decreased growth, muscle weakness, and death with marked changes in both calcium andphosphorus metabolism.Bentonite did not cause fibrosis after 1 year exposure of 60 mg dust (<5 um) in a rat study. However, in asecond rat study, where 5 um particles were intratracheally instilled at 5, 15 and 45 mg/rat, dose-relatedfibrosis was observed. Bentonite clay dust is believed to be responsible for bronchial asthma in workers at aprocessing plant in USA.Ingestion of bentonite without adequate liquids may result in intestinal obstruction in humans.Hypokalaemia and microcytic iron-deficiency anaemia may occur in patients after repeat doses of clay. Chronicingestion has been reported to cause myositis.

Section 12 - ECOLOGICAL INFORMATION

BENTONITE:RESIDUAL OILS, PETROLEUM, SOLVENT-DEWAXED:■ DO NOT discharge into sewer or waterways.

RESIDUAL OILS, PETROLEUM, SOLVENT-DEWAXED:■ for lubricating oil base stocks:Vapor Pressure Vapor pressures of lubricating base oils are reported to be negligible. In one study, theexperimentally measured vapour pressure of a solvent-dewaxed heavy paraffinic distillate base oil was 1.7 x10exp-4 Pa . Since base oils are mixtures of C15 to C50 paraffinic, naphthenic, and aromatic hydrocarbonisomers, representative components of those structures were selected to calculate a range of vapor pressures.The estimated vapor pressure values for these selected components of base oils ranged from 4.5 x 10exp-1 Pato 2 x 10exp-13Pa. Based on Dalton's Law the expected total vapour pressure for base oils would fall wellbelow minimum levels (10exp-5 Pa) of recommended experimental procedures.Partition Coefficient (log Kow): In mixtures such as the base oils, the percent distribution of thehydrocarbon groups (i.e., paraffins, naphthenes, and aromatics) and the carbon chain lengths determines in-part the partitioning characteristics of the mixture. Generally, hydrocarbon chains with fewer carbon atomstend to have lower partition coefficients than those with higher carbon numbers .However, due to theircomplex composition, unequivocal determination of the log Kow of these hydrocarbon mixtures cannot be made.Rather, partition coefficients of selected C15 chain-length hydrocarbon structures representing paraffinic,naphthenic, and aromatic constituents in base oil lubricants were modelled . Results showed typical log Kowvalues from 4.9 to 7.7, which were consistent with values of >4 for lubricating oil basestocksWater Solubility:When released to water, base oils will float and spread at a rate that is viscositydependent. While water solubility of base oils is typically very low, individual hydrocarbons exhibit a widerange of solubility depending on molecular weight and degree of unsaturation. Decreasing molecular weight

continued...



CD 2011/2 of 16Section 12 - ECOLOGICAL INFORMATION

(i.e., carbon number) and increasing levels of unsaturation increases the water solubility of thesematerials. As noted for partition coefficient, the water solubility of lubricating base oils cannot bedetermined due to their complex mixture characteristics. Therefore, the water solubility of individual C15hydrocarbons representing the different groups making up base oils (i.e., linear and branched paraffins,naphthenes, and aromatics) was modelled. Based on water solubility modelling of those groups, aqueoussolubilities are typically much less than 1 ppm. (0.003-0.63 mg/l)Environmental Fate:Photodegradation: Chemicals having potential to photolyse have UV/visible absorption maxima in the range of290 to 800 nm. Some chemicals have absorption maxima significantly below 290 nm and consequently cannotundergo direct photolysis in sunlight (e.g. chemicals such as alkanes, alkenes, alkynes, saturated alcohols,and saturated acids). Most hydrocarbon constituents of the materials in this category are not expected tophotolyse since they do not show absorbance within the 290-800 nm range. However, photodegradation ofpolyaromatic hydrocarbons (PAHs) can occur and may be a significant degradation pathway for theseconstituents of lubricating base oils. The degree and rate at which PAHs may photodegrade depend upon whetherconditions allow penetration of light with sufficient energy to effect a change. For example,polycyclicaromatic compounds (PAC) compounds bound to sediments may persist due to a lack of sufficient lightpenetrationAtmospheric gas-phase reactions can occur between organic chemicals and reactive molecules such asphotochemically produced hydroxyl radicals, ozone and nitrogen oxides. Atmospheric oxidation as a result ofradical attack is not direct photochemical degradation, but indirect degradation. In general, lubricatingbase oils have low vapour pressures and volatilisation is not expected to be a significant removal mechanismfor the majority of the hydrocarbon components. However, some components (e.g., C15 branched paraffins andnaphthenes) appear to have the potential to volatilise Atmospheric half-lives of 0.10 to 0.66 days have beencalculated for representative C15 hydrocarbon components of lubricating base oilsStability in Water: Chemicals that have a potential to hydrolyze include alkyl halides, amides, carbamates,carboxylic acid esters and lactones, epoxides, phosphate esters, and sulfonic acid esters. Becauselubricating base oils do not contain significant levels of these functional groups, materials in thelubricating base oils category are not subject to hydrolysisChemical Transport and Distribution in the Environment : Based on the physical-chemical characteristics ofcomponent hydrocarbons in lubricating base oils, the lower molecular weight components are expected to havethe highest vapour pressures and water solubilities, and the lowest partition coefficients. These factorsenhance the potential for widespread distribution in the environment. To gain an understanding of thepotential transport and distribution of lubricating base oil components, the EQC (Equilibrium Criterion)model was used to characterize the environmental distribution of different C15 compounds representingdifferent structures found in lube oils (e.g., paraffins, naphthenes, and aromatics). The modelling foundpartitioning to soil or air is the ultimate fate of these C15 compounds. Aromatic compounds partitionprincipally to soil. Linear paraffins partition mostly to soil, while branching appears to allow greaterdistribution to air. Naphthenes distribute to both soil and air, with increasing proportions in soil forcomponents with the greater number of ring structures. Because the modelling does not take into accountdegradation factors, levels modelled in the atmosphere are likely overstated in light of the tendency forindirect photodegradation to occur.Biodegradation: The extent of biodegradation measured for a particular lubricating oil basestock isdependent not only on the procedure used but also on how the sample is presented in the biodegradation test.Lubricant base oils typically are not readily biodegradable in standard 28-day tests. However, since the oilsconsist primarily of hydrocarbons that are ultimately assimilated by microorganisms, and therefore inherentlybiodegradable. Twenty-eight biodegradability studies have been reported for a variety of lubricating baseoils. Based on the results of ultimate biodegradability tests using modified Sturm and manometricrespirometry testing the base oils are expected to be, for the most part, inherently biodegradable.Biodegradation rates found using the modified Sturm procedure ranged from 1.5 to 29%. Results from themanometric respirometry tests on similar materials showed biodegradation rates from 31 to 50%. Biodegradationrates measured in 21-day CEC tests for similar materials ranged from 13 to 79%.Ecotoxicity:Numerous acute studies covering fish, invertebrates, and algae have been conducted to assess the ecotoxicityof various lubricating base oils. None of these studies have shown evidence of acute toxicity to aquatic

organisms. Eight, 7-day exposure studies using rainbow trout failed to demonstrate toxicity when tested up tothe maximum concentration of 1000 mg/L applied as dispersions. Three, 96-hour tests with rainbow trout alsofailed to show any toxic effects when tested up to 1000 mg/L applied as dispersions. Similarly, three 96-hourtests with fathead minnows at a maximum test concentration of 100 mg/L water accommodated fractions (WAF)showed no adverse effects. Two species of aquatic invertebrates (Daphnia magna and Gammarus sp.) were exposedto WAF solutions up to 10,000 mg/L for 48 and 96-hours, respectively, with no adverse effects being observed.Four-day exposures of the freshwater green alga (Scenedesmus subspicatus) to 500 mg/L WAF solutions failed toshow adverse effects on growth rate and algal cell densities in four studiesMultiple chronic ecotoxicity studies have shown no adverse effects to daphnid survival or reproduction. In 10of 11 chronic studies, daphnids were exposed for 21 days to WAF preparations of lubricating base oils with noill effects on survival or reproduction at the maximum concentration of 1000 mg/L. One test detected areduction in reproduction at 1000 mg/L. Additional data support findings of no chronic toxicity to aquaticinvertebrates and fish. No observed effect levels ranged from 550 to 5,000 mg/L when tested as eitherdispersions or WAFs.The data described above are supported by studies on a homologous series of alkanes. The author concludedthat the water solubility of carbon chains .C10 is too limited to elicit acute toxicity. This also was shownfor alkylbenzene compounds having carbon numbers .C15. Since base oils consist of carbon compounds of C15 toC50, component hydrocarbons that are of acute toxicological concern are, for the most part, absent in thesematerials. Similarly, due to their low solubility, the alkylated two to three ring polyaromatic components inbase oils are not expected to cause acute or chronic toxicity. This lack of toxicity is borne out in theresults of the reported studies.The effects of crude and refined oils on organisms found in fresh and sea water ha been extensively reviewed.sea water. Where spillages occur the non-mobile species suffer the greatest mortality, whereas fish speciescan often escape from the affected region. The extent of the initial mortality depends on the chemical natureof the oil, the location, and the physical conditions, particularly the temperature and wind velocity. Mostaffected freshwater and marine communities recover from the effects of an oil spill within a year. Theoccurrence of biogenic hydrocarbons in the world's oceans is well recorded. They have the characteristicisoprenoid structure, and measurements made in water columns indicate a background concentration of 1.0 to 10ul/l. The higher molecular weight materials are dispersed as particles, with the highest concentrations ofabout 20 ul/l occurring in the top 3 mm layer of water.A wide variation in the response of organisms to oil exposures has been noted. The larvae of fish andcrustaceans appear to be most susceptible to the water-soluble fraction of crude oil. Exposures of planktonand algae have indicated that certain species of diatoms and green algae are inhibited, whereasmicroflagellates are not.For the most part, molluscs and most intertidal worm species appear to be tolerant of oil contamination.
