Hazardous Communication & Laboratory Safety

Standards, Regulations, LawsRequires manufacturers or importers to assess the hazards of substances which they produce or import about the hazardous substances to which they may be exposed, by means of a hazard communication program, labels and other forms of warning, material safety data sheets, and information and training. Title 8 CCR, 5191 & 5194You have the right to know!

2Whistleblower protection Act - California Government Code Article 3 section 8547 : employees should be free to report waste, fraud, abuse of authority, violation of law, or threat to public health without fear of retribution .

OSHA General Duty Clause- each employer shall furnish to each of his employees a place of employment which is free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees. IDLH

Laboratory & Hazard Communication Standard

California statutes are chaptered bills. A bill is chaptered if it passes both house and senate and then signed by governor.

Safety Data Sheets

3The law requires that MSDSs be provided to users by the manufacturer and distributors of Chemicals.Best general source of information available in regards to the precautions that should be followed due to the known hazards of a particular chemical.

MSDSs must addresses the hazards of a chemical in all possible situations including industrial (tankers trucks, industrial operations) operations and transportation accidents. For this reason some of the information may not be relevant to the handling and use of that chemical in a laboratory setting due to the volume used

Ex. Acetone spill- MSDS says to use a SCBA , Heavy gloves and rubber boots. These precautions would not be necessary in a laboratory scale spill.

Limitations - Worse Case Scenario's-quality varies widely-there exists vague and unqualified generalizations-many list all conceivable health hazards-lack of confidence in the relevance of an MDSD in lab scale work due to the need to address large scale situations.

Physical Hazards

Health Hazards

Exploding BombHealth HazardEnvironmentalCompressed GasesFlame over CircleExclamation CorrosiveFlame Skull & Crossbones4Explosives - contain both an oxidizer (O2) and a reducing agent (fuel) which makes up 2 of the 3 sides of the fire triangle. All you need is heat or an ignition source.Ammonium nitrate = fertilizer.Oklahoma bombing.

FLAMMABLES - Concentrated vapors of flammable liquids are heavier than air and can travel a considerable distance. Ex. Alcohols, acetone, Ethers.-Vapors are like fingers searching for a source... under doors, through ventilation systems, and then lo and behold a bunsen burner.

WATER REACTIVE Alkali metals: Lithium, sodium metal

CLICKCOMPRESSED GAS - if a cylinder falls the valve stem is knocked off, the pressure provides torpedo actions through the walls down the hallways. -if a cylinder is not in use we ask the labs to store with the storage caps on. To prevent such an occurrence. We also ask that they are restrained with chains and cloth tie downs at 1/3 and 2/3 the height for fire and earthquake issues

Oxidizers Oxygen, Nitric Acid, Hydrogen PeroxideOrganic Peroxide- diethyl ether peroxide, Tetrahydrofuran (THF)Oxidizing Agents -perchloric and chromic acids

Shock Sensitive Chemicals - Ammonium Nitrate, Dry Picric Acid- Glider port in La Jolla

6Can you trust your neighbor????

It is essential for each laboratory worker to be proactive to ensure the laboratory is a safe working environment. This attitude begins with wearing the proper PPE when working with hazardous materials or entering an area where they are used. It is the responsibility of the institution to ensure that the appropriate equipment is provided.

29 CFR 1910.1328CCR 3401

Masks, eye protection, gloves, aprons, and other protective equipment and clothing are designed to protect you while you work. USE THEM! Emergency EquipmentFirst-Aid kitsSpill kitsSafety showersFree AccessEyewash stationsFire extinguishersEmergency ExitsStorage areas clear

7Know where it is located and how to use it.

During an emergency it is too late to find a fire ext. or know how to use it.OrFind an eyewash while you have acid in your eyes.

Eye InjuryRinse eyeball and inner surface of eyelid for 20 MinutesForcibly hold eye open Obtain medical attentionReport incident to PI/IST/Supervisor (University Police)

Working quickly, you flicked open an eppendorf tube and several droplets of phenol hit your eye

8You only have one set of eyes.How could this have been prevented?-safety glasses, goggles, or a face shield

Eyewash -.4gpm @ 15min = 6 gallons of H2O in your eye.Minor Spill ResponseLet the people around you know and inform your ProfessorAssess situation: Injuries priorityDe-energize ignition sourceBarricade spill areaDon PPEConfine/Contain spill areaWaste collection

9You may be the primary person to come across a release. Your job is to notify & get out. You may see it , smell it or equipment may note it. Questions to ask yourself. -unusual odor complaint in your area -unusual containers that are out of place.

1-Alert those that would be affected by the spill, especially your neighbor2-attend to injured= shower, eyewashes (15min), lukewarm water ( HOT opens pores, COLD closes pores) and soap for contaminated skin. SILKWOOD. get med attn3 Denenrgize sources- bunsen burners, hot plates 4-Barricade Spill area- minimize traffic through spill area5- DON PPE -use proper protective clothing for operation6- Confine & contain - use spill pillows, dry absorbent , prevent release to outer areas.7- Waste- this is done by safety office. techs who are appropriately trained. Collect it and label contents appropriately P.A.S.S.Pull the pinAim at base of fireSqueeze the handleSweep side to side Position yourself between the fire and escape routeHave a back-upDo not turn your back to the fireAlert key personnel regarding the incident

Laboratory Fire

10PASS MethodEmergency ProceduresInform lab teacherCall police in the event of an injury 911 or 760.750.4567

Located on the wall of the lab, usually by the phone.

Bio-Hazardous MaterialsUniversal Precautions - Treat all blood and bodily fluids as if they are contaminatedUse of proper PPESigns - shall be posted at the entrance to work areas and on units storing Bio-haz materials.Prepare WASTE Regulatory requirements.Double bagged (RED) Keep bags in closed, rigid container off of the floor

12Universal Precautions-...all human blood and certain human body fluids are treated as if known to be infectious for HIV, HBV, and other bloodborne pathogens.

For this reason dont recap any needles use the proper sharps container and discard the whole thing. Needlesticks are still a big issue in health care.

-Waste labeling-biohazard warning, generator label or preprinted bags with your name and address, double red bagged.-Orange bags are designated for CAL -TRANS. Waste should remain contained (in a secondary in case of a breach), not overflowing and off the floor.

Bio- HazardEmerald Energy Program

All BSL-2 waste must be discarded in the biohazardous waste

Other Waste CollectionsBroken GlassEmpty Glass Bottles

14Extension cords- daisy chained: one extension cord connected to another extension cord. Temporary wiring

Laboratory Work Practices Wear appropriate PPEKeep fume hood sash at the appropriate levelNo Children and petsLab policyLabel containersKeep closed/sealed EquipmentInspection routinelyReport broken or damaged lab wareClean up spills Wash your hands after working with hazardous materials

15Children and pets Lower PELs

Properly label containers For many reasons : coworkers, Inspectors, and waste managers

containers closed Its the law & it mitigates accident and exposure

Must Wear Closed Toed ShoesNo Eating or Drinking in the laboratory

It is recommended that you

Wear pants, safety glasses and a lab coat Applying cosmetics should be prohibited
