Gives chemical nature of the substance;
Physical properties
First aid measures to be taken
Fire fighting measures
Accidental release measures
Handling, storage and Personal Protective Equipment to worn;
Disposal Requirements
Regulatory information including risk phrases and safety phrases
Sources of Harm
Requires risk assessments be done;
Suitable controls put in place to ensure workers safety;
Legal limits for certain chemicals;
Requires LEV be tested every 14 months;
Identifies any health surveillance that is required;
Requires face fitting of Respiratory Protective Equipment (RPE);
Duty to ensure that information, training and supervision is provided;
Emergency arrangements in place if required.
Control of Substances Hazardous to Health
Control of Substances Hazardous to Health Regulations (COSHH) 2002
Material Safety Data Sheet
NOTE – a Safety Data Sheet is NOT a COSHH risk assessment. It identifies the hazards but the COSHH risk assessment will identify what you do with it and how you intend to control the hazards
Any material or substance with the potential to cause illness or injury to people who come into contact with it

A substance may be hazardous because it is explosive, flammable, harmful, irritant, corrosive, toxic, produces a chemical reaction or an allergic reaction
Harmful Substances

Used directly in the work process
Paints & thinners, solvents, cleaning agents

Generated during the work process
Dust, gases, fumes

Naturally occurring substances
Grain dust, silica, asbestos, flour

Biological Agents
Spores, bacteria, viruses, moulds, fungus
Acute – Chronic
Lung disease
Skin disease - dermatitis
Irritation – skin, eyes, lungs
Infectious diseases - hepatitis
Neurological damage – lead, mercury
Birth defects
Impaired fertility
Dermatitis from contact with harmful chemicals
Cancer causing asbestos dust
Burns caused by lime powder
Harmful Effects
A pensioner died six days after drinking a detergent liquid she was given instead of blackcurrant cordial. The elderly woman, was one of 10 people given dishwasher rinse to drink by mistake at a private care home in Slough, Berkshire.

Joan Walters, 80, died earlier in the week after being taken to Wrexham Park Hospital, Slough. Eight other residents of the Lady Astor Court nursing home were treated after drinking the purple detergent liquid.

A care assistant is believed to have confused two similarly packaged bottles.
Romney Marsh Potato Co fined £3,000 + £2,100 costs and director N Winmill fined £750 + £528 costs.
Pesticide were decanted into a milk carton and stored in an eating area. Worker injured after assuming carton contained orange juice. The company was found to have "no safe system of work or training" and the "director failed to act"

Hallmark Healthcare fined £40,000 + £6,000 costs.

Elderly resident with Alzheimer's drank from a jug containing sodium hydroxide-based liquid. Jug left unattended in an office accessible to residents. The company were found to have a "lack of competence" and "poor management".
Step 1 Assess the risk
Step 2 Decide what precautions are needed
Step 3 Prevent or control exposure
Step 4 Ensure control measures are used
Step 5 Monitor the exposure
Step 6 Carry out health appropriate surveillance
Step 7 Plan for accidents and emergencies
Step 8 Provide employees with information, training and supervision
The 8 Steps to Reducing Risk
Identify the hazardous substances present in the workplace:

Warning labels
Material Safety Data Sheets (MSDS)
HSE website – EH40/2005
Assess the Risks
Chemical Hazard Symbols
Factors to consider include:
Varying concentrations over time
Duration of exposure
Accurate measuring of quantities
Changes to form of substance
The term used for small particles of a solid suspended in the air

The term used to describe the gaseous state of solids or liquids

Formed when solid vapours condense in the atmosphere

Small liquid droplets that form when a liquid is atomised

Solid To Dust – Asbestos & Hardwood Dust

Liquid To Vapour – Petrol

Solid To Fumes – Lead Oxide, Chlorine gas

Liquid To Mist –Paint Spray, Pesticides

Ingestion – Food/Drink

Absorption – Skin/Cuts


Routes of Entry Into Body
Industry sector best practice
Information on Material Safety Data Sheets
Information on labels
In house policy and guidance
Specialist advise and guidance
Government advice (Dept of Health, HSE etc)
Hierarchy of Controls

Reduce Exposure – Engineering Controls
Reduce Exposure – Procedural Controls
Personal Protective Equipment
Welfare Facilities
Prevent or Control Exposure
Testing of equipment including PPE
Review of Safe Systems of Work
Review of Risk Assessments
Systems for reporting defects
Accident and incident reporting
Refresher-Update training

Mainly concerned with measuring the concentration of hazardous substances in the air likely to be breathed by employees or others

May not be required if other methods of adequately controlling employees exposure can be demonstrated
Monitor Exposure
This is usually only undertaken in specific instances where:

There is an identifiable disease or other identifiable adverse health outcome linked to the work
The disease or health effect may be related to exposure
There is a likelihood that the disease or health effect may occur
There are valid techniques for detecting indications of the disease or health effects exposure to a substance linked to a particular disease or adverse health effects

Health Surveillance
Applies to circumstances where the risk of an accident or emergency involving exposure to a hazardous substance goes beyond the risks associated with normal day to day work

Plan for Accidents and Emergencies
Legal requirement to provide in a format likely to be understood
Updated as required
Based on required level of competency
General Approach – Low Level
Hazard specific – WELs
Provided by a competent person

Provide Employees with Suitable Information- Instruction - Training
Always check labels before use
Only store in suitable and labelled containers
Store chemicals in a secure area
Never mix chemicals without appropriate advice & guidance
Always wear appropriate PPE correctly
Clear up spillages immediately
Follow Safe Systems of Work
Report any symptoms of ill health immediately
Report any operational or equipment failures
Golden Rules for CoSHH Safety
A chemical distribution company in Leicestershire found itself in the dock after an employee unwittingly mixed two chemicals together during a routine tidy-up, causing toxic and potentially explosive fumes to billow around the company’s yard, close to the M1
Amount of Substance
Changes in Physical Form
Form of Substance
Solid – Liquid – Gas
Decide What Precautions are Needed
Ensure That Control Measures Are Used And Maintained
Harmful Effects
