• Risk Assessment - Regulation 6
• Health Surveillance - Regulations 11
EH40/2005 Workplace Exposure Limits (WEL)
• Containing the list of workplace exposure limits for use with the Control
of Substances Hazardous to Health Regulations 2002 (as amended)
The Classification, Labelling and Packaging of Substances
and Mixtures Regulations 2008 (CLP) adopts GHS within
the EU

5. Control of Substances Hazardous to
Health (COSHH)
Any substance that may cause YOU harm, injury or ill health:
• Chemicals: Burns, Infection, Irritant.
• Dust: Breathing difficulties, Explosive.
• Biological Agents: Organ problems. Birth defects.
• Carcinogenic: Substances that promote cancer.
• Sensitizers: Where contact with a certain substance has an instant
adverse reaction.

6. Control of Substances Hazardous to
Health (COSHH)
Any substance that may cause YOU harm, injury or ill health:
• Chemicals: Burns, Infection, Irritant.
• Dust: Breathing difficulties, Explosive.
• Biological Agents: Organ problems. Birth defects.
• Carcinogenic: Substances that promote cancer.
• Sensitizers: Where contact with a certain substance has an instant
adverse reaction.

7. Control of Substances Hazardous to
Health (COSHH)
Main Classification system:
• Irritant Chemicals that may cause irritation
• Corrosive Chemicals that may destroy tissue on contact
• Harmful Chemicals that may cause damage to health
• Toxic Chemicals that at low levels cause damage to health
• Very toxic Chemicals that at very low levels cause damage to health
• Carcinogenic Chemicals that may cause cancer or increase its incidence
• Mutagenic Chemicals that induce heritable genetic defects or increase their incidence
• Reproductive Chemicals that produce or increase the incidence on non-heritable
toxin effects in progeny and/or an impairments in reproductive functions
or capacity

8. Control of Substances Hazardous to
Health (COSHH)
Control measures identified as required will conform to the below, in descending order of
preference:
1. Eliminate risks e.g. by avoiding the use of certain processes.
2. Substituting a less hazardous material
3. Improving existing controls by, for example, providing better extraction facilities
4. Combating risks at source e.g. by engineering controls or positively isolating,
separating individuals from the hazardous part or substance
5. Minimising the risk by the design of suitable systems of work.
6. As a last resort minimising the risk by the use of personal protective equipment.

• PPE must be cleaned and stored in a safe place.
• Must be USED and ENFORCED.
• Provided free of charge.
• Sign PPE Issue Record (EBS-DOC-101 PPE Issue Record)

24. PPE Types

25. Example Standard explained.
EN ISO 20345:2011 is not as complicated to
understand as it first appears, and it specifies
the basic/ additional safety footwear
requirements to meet the standard.
EN - This is the current applicable standard
across Europe.
ISO - All footwear PPE products must meet
the minimum safety standards as defined by
the International Organisation for
Standardisation.
20345 - This is the assigned legislation
number.
2011 - This is the year the safety standard
around footwear was updated.
This applies to other PPE.

Safe Handling - Dangerous Reactions

36. Storage of Deliveries
All deliveries will be supervised by a competent person capable of dealing with
any spills or other incidents that may occur. The level of all storage tanks will be
checked before delivery to prevent overfilling and to ensure that the product is
delivered to the correct tank. All deliveries must be stored away straight away
and not left in the yard. Inform the hygiene team straight away.
Fuel, oil, ingredients and chemical tanks must be sited on an impervious base,
within a secure bund. The base and bund must be impermeable to the
substance being stored and have sufficient capacity for daily use and for the
receipt of additional deliveries. Leaking damaged or empty tanks/ drums must
be removed from the site immediately and disposed of via a licensed waste
disposal contractor. All bowsers must be bunded to prevent any accidental
spills.

37. Storage of Deliveries

use of the chemicals

40. Mixing of Chemicals
Don’t
• Use any chemicals without understanding the
proper documentation
• Use any chemical that has no label attached to the
container

dilution
• Follow application instructions
• First Aid procedures
Remember

52. Risk Assessment Process
A Risk Assessment is….
Simply a careful examination of what, in the workplace, could cause
harm to people, so that a decision can be made as to whether the
precautions taken are satisfactory or whether more should be done to
prevent harm

53. Definitions
Hazard
Harm
Risk
anything that may cause harm, such as
chemicals, electricity, working from ladders, or
an open drawer
includes ill-health and injury; damage to
property, plant, products, or the environment;
and production losses or increased liabilities
the chance, high or low that somebody could be
harmed by a hazard, together with an indication of
how serious the harm could be

54. Risk Assessment Process

55. Identify the Hazards
• Cover all substances
• Handled, stored and used for processing
• Fumes, vapours, dusts etc.
• Maintenance, cleaning, and repair work
• Wastes, residues, scrap etc.
• Another employer’s employees' activities

56. Identify the Hazards
• The form off the substance (e.g. solid, liquid, gas, etc.)
• Nature of the substance (e.g. raw material, by-product, waste)
• The hazards presented(e.g. irritant, corrosive, toxic, etc.)
• Quantity to be used or created
• Concentration of hazardous substance
• WEL, if assigned
• Nature of work (e.g. painting with brush or spray painting)
• Duration and frequency of the work
• Routes of entry into the human body

57. Workplace Exposure Limits
Maximum concentration of an
airborne substance averaged over a
reference period (time-weighted
average - TWA) to which employees
may be exposed by inhalation
Short-term exposure limits (STELs)
15 minute reference period
Protect against acute adverse
health effects
Long-term exposure limits (LTELs)
8 hour reference periods
Controls health effects arising
from prolonged or accumulated
exposure

58. Decide who might be harmed
• Don’t forget
• Maintenance workers
• Office staff
• Night cleaners
• Security guards
• Members of the public
• Employees who may be at an increased risk
Consider all Groups of People

59. Evaluate the Risks and Decide on
Precautions
• Estimate employee exposure
• Concentration likely to be produced
• Effort needed to do the work (breathing rate)
• Effect of any existing preventive or control measures
• Atmospheric sampling and measurement
• Comparison with WEL
• Control measures in accordance with the principles of good
practice

60. Principles of Good Practice
Minimise
emission, release
and spread
Consider all
relevant routes of
exposure
Control measures
proportionate to
the risk
Most effective
and reliable
control options
Suitable PPE
Regularly check
and review
control measures
Inform and train
all employees
Do not increase
the overall risk to
health and safety

61. Evaluate the Risks

62. Hierarchy of Control

63. Record the Findings and Implement
Them
• Effective statement of hazards and risks
• Evidence that all relevant factors have been systematically
considered
• Evidence that measures have been implemented to prevent
exposure or to achieve and maintain adequate control of
exposure
• No set format

64. Review the Risk Assessment and Update
if Necessary
• Frequency of review determined by type of risk, the work and
likelihood of change
• Immediate review if
• Evidence no longer valid
• Significant change in the circumstances of work

65. COSHH Risk Assessment
Example of COSHH Risk
Assessment Template

66. Benefits of Health Surveillance
• Early identification and treatment of occupational disease
• Workforce health statistics
• Feedback mechanism on effectiveness of control measures
• Due diligence
