Video
• Thanks to an Innovative Project Grant from the American Chemical Society to the Division of Chemical Health and Safety, we are able to share the video below with the research chemistry community.
• The video is 2 minutes and 12 seconds long and provides an overview of the reasons that conducting a risk assessment of laboratory work is so important to maintaining situational awareness as laboratory work proceeds.

Requirements of COSHH Occupational Health
& Safety Service
Our Duties• Identify hazards and assess risks to health• Select control measures to prevent or control exposure• Monitor exposure• Provide health surveillance• Provide information, instruction and training• Plan for all reasonably foreseeable emergencies• Ensure control measures are implemented and maintained
We follow this

Hazard Information Occupational Health

Chemical labels have changed
The outgoing system – CHIP• Risk Phrases - R34, causes burns• Indications of Danger –corrosive.
Some have more then one category (e.g. carcinogenic category 1, 2 and 3)
• Safety Phrases - S39, wear eye/face protection
The incoming system – GHS/CLP• Hazard Statements - H314, causes
severe burns and eye damage• Hazard Classes - category 1A, 1B
and 2 carcinogens• Precautionary Statements - e.g.
P280: Wear protective gloves/protective clothing/eye protection/face protection
Hazard Information Occupational Health

• Harmful / Irritant
• Corrosive
• Oxidising
• Acutely toxic
• Flammable
• Explosive
• Hazardous to the aquatic environment

Hazard Information
If you need to acquire, use or store any chemicals references in these guidance documents there could be duty on the University to obtain the necessary certificates and Licences, ensure that the substance is stored safety and securely, and to keep records.
If this is relevant to you then follow the process in the Guidance

Carcinogen Registration Occupational Health
& Safety Service
Carcinogens are given special consideration under COSHH and must be substituted with a less toxic alternative where practicable.
Register these:• carcinogen category 1A or category 1B according to the GHS/CLP regulations.• hazard statement H350 or H350i according to the GHS/CLP regulations.• schedule 1 of COSHH.• listed as a carcinogen in document EH40

The aim of this guidance is aid compliance with the Control of Substances Hazardous to Health Regulations 2002 (COSHH) (as amended) and establish good safety practice when working with nanomaterials. It is based heavily on:
• Working Safety with Nanomaterials in Research and Development (Second Edition) which was developed by the UK NanoSafety Group (UKNSG) and is endorsed by the Health and Safety Executive (HSE).
• HSG272 Using nanomaterials at work which is guidance produced by the HSE
This guidance should be used in conjunction with OHSS: H&S Guidance 401.1 Control of Substances Hazardous to Health (COSHH): Guidance to Risk Assessment.
Controls Occupational Health
& Safety Service
Fume hood – which chemical, what part of the protocol?Handle in accordance with good industrial hygiene and safety practice
Eye/face protectionFace shield and safety glasses Use equipment for eye protection tested and approved underappropriate government standards such as NIOSH (US) or EN 166(EU).Skin protectionHandle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique(without touching glove's outer surface) to avoid skin contact with this product. Dispose ofcontaminated gloves after use in accordance with applicable laws and good laboratory practices.Body ProtectionComplete suit protecting against chemicals, The type of protective equipment must be selectedaccording to the concentration and amount of the dangerous substance at the specific workplace.Respiratory protectionWhere risk assessment shows air-purifying respirators are appropriate use a full-face particlerespirator type N100 (US) or type P3 (EN 143) respirator cartridges as a backup to engineeringcontrols. If the respirator is the sole means of protection, use a full-face supplied air respirator. Userespirators and components tested and approved under appropriate government standards suchas NIOSH (US) or CEN (EU).

Controls Occupational Health
& Safety Service
• Required to reach an informed judgement about the risks
• Failure or deterioration of the control measures could result in a serious health effect (toxicity or extent of exposure)
• WEL for a substance might be exceeded; • Change in conditions means that adequate
control of exposure is no longer being maintained • To check the effectiveness of the control
measures
• Carcinogens• Asthmagens• Respiratory sensitisers and allergens (including,
but not limited to, substances that have been assigned the hazard codes H317 or H314)
• Other substances for which there is a likelihood that an identifiable disease or adverse health effect will result from, or may be related to, exposure
Residual Risk Occupational Health
& Safety Service
Has risk been reduced to as low as reasonably practicable?
Not acceptable – more controls needed
Work can proceed
Acceptable or not?
DSEAR (Experimental) Occupational Health
& Safety Service
• Consideration of the hazards associated with chemical reactions, unstable or pyrophoric substances and explosive atmospheres.
• Controls required to protect health risks under COSHH my not be sufficient to control the fire and explosion risk.
Thermal Runaway‘A reaction where an increase in temperature changes the conditions of the reaction in a way that leads to a further rapid increase in temperature.’
Explosive Atmosphere‘A mixture of dangerous substances with air, under atmospheric conditions, in the form of gases, vapours, mist or dust in which, after ignition has occurred, combustion spreads to the entire unburned mixture.’
DSEAR risk and controls Occupational Health
& Safety Service
DSEAR (Full Risk Assessment)
• A specific DSEAR risk assessment must be carried out if:
• the work activity involves the use or storage of pressurised flammable gas cylinders such as acetylene or hydrogen
• very large quantities of flammable substances are involved where the recommended limits for storage of flammable substances are exceeded (50 litres for extremely or highly flammable substances and flammable liquids with a flashpoint below the maximum ambient temperature of the working area, 250 litres for other flammable liquids with a higher flashpoint of up to 55°C)
• the work activity involves the use of explosives
• the work activity is likely to create an explosive atmosphere even after the application of controls stated in the COSHH risk assessment
• the work activity involves the use of flammable/oxidising/explosive substances only and not substances hazardous to health as defined by COSHH

Emergency Planning Occupational Health
& Safety Service
Evacuate? Call 999 as the first number to ring. Security should then be informed that the Fire and Rescue Service have been contacted directly and be provided with details of the incident where possible.
What do I do with my completed
COSHH form? Occupational Health
& Safety Service
• Keep a record• Implement and maintain control measures• Have a copy on hand in case of emergencies• Share the information – everyone should know the hazards
and risks, controls they should use and know what to do in an emergency
• Review every 2 years or immediately if:• You make changes to the work activity• There is new information • It is no longer valid• After an emergency
