Cards in this deck (14)
- 1There are several pieces of legislation that control the supply and use of hazardous substances in the UK. These are (6)Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH)
Classification, Labelling and Packaging of Substances, and Mixtures (CLP)
Chemical (Hazard, Information and Packaging for Supply) Regulations 2009
Control of Substances Hazardous to Health Regulations 2002, as amended
Control of Lead at Work Regulations 2002
Control of Asbestos Regulations 2012 - 2REACH is designed to: (7) Improve information in the supply chain - many substances are data poor and
this can lead to inadequate risk assessments.
Promote better risk management measures.
Facilitate compliance with CoSHH.
Encourage the use of safer alternatives for CMR substances.
Allow the free movement of substances on the EU market.
Question the need for animal testing.
Lead to improvements in occupational health. - 3Under REACH, each producer and importer of chemicals in volumes of 1 tonne or more per year and will have to register each chemical with the EU Chemicals Agency (the ECHA), submitting information on: (3) properties
uses
safe ways of handling them. - 4Use-specific authorisation will be required for chemicals that cause: 4 Cancer
Mutations
Problems with reproduction.
It is also required for those that accumulate in human bodies and the environment. - 5ECHAEuropean Chemicals Agency
- 6DNELderived no effect level
- 7Classification is the process of: 2 Deciding what kind of hazard the chemical has.
Explaining the hazard by assigning a simple sentence that describes it (known
as a ‘risk phrase’ or ‘R-phrase’ for short). - 8If a dangerous chemical is supplied in a package, the package must be labelled. The aim of the label is to: 2 Inform anyone handling the package or using the chemicals about its hazards.
Give brief advice on what precautions are needed. - 9CoSHH defines a ‘substance hazardous to health’ as one which: 51) Is listed in the approved supply list (ASL) as dangerous for supply within the
meaning of the CHIP Regulations and for which an indication of danger
specified for the substance is very toxic, toxic, harmful, corrosive or irritant.
2) The Health and Safety Executive has approved a workplace exposure limit
(WEL).
3) Is a biological agent.
4) Is dust (other than those covered in (a) or (b) above) present at a concentration
in air equal to or greater than:
10 mg/m
3
, as a time-weighted average over an 8-hour period, of inhalable
dust
4 mg/m
3
, as a time-weighted average over an 8-hour period, of respirable
dust
5) Because of its chemical or toxicological properties and the way it is used or is
present at the workplace creates a risk to health. - 10A summary of the CoSHH duties 86. Risk assessment
7.Prevention or control of
exposure
8. Use of control measures
9. maintenance, examination and
test of control measures
10. Monitoring exposure at
workplace
11. Health surveillance
12. Information, training etc.
13. Arrangements to deal with
accidents, incidents and
emergencies - 11Under COSHH, there is mandatory monitoring for:2Vinyl chloride monomer (VCM)
Spray given off from vessels at which
an electrolytic chromium process is
carried on, except trivalent chromium - 12Under COSHH, Health surveillance of employees should be carried out where: 4 An identifiable disease or adverse health effect may be related to the exposure.
There is a ‘reasonable likelihood’ that the disease or health effect may occur
under the particular conditions of work.
Valid techniques exist for detecting indications of the disease of health effect.
The technique presents a low risk to the employee. - 13Information, instruction and training (Regulation 12) This regulation demands that all employees are liable to be exposed to hazardous substances, they are provided with suitable and sufficient information, instruction and training, including: 6 Details of the hazardous substances including:
- Names of substances and the risk that they present to health
- Any relevant occupational exposure standard, maximum exposure limit or
similar occupational exposure limit
- Access to any relevant safety data sheet.
Other legislative provisions which concern the hazardous properties of those
substances.
Significant findings of risk assessment.
Appropriate precautions and actions to be taken by the employee in order to
safeguard himself and other employees at the workplace.
Results of any monitoring of exposure and, in particular, in the case of a
substance hazardous to health for which a maximum exposure limit has been
approved, the employee or his representatives shall be informed forthwith, if the
results of such monitoring show that the maximum exposure limit has been
exceeded.
Collective results of any health surveillance undertaken in a form calculated to
prevent those results from being identified as relating to a particular person. - 14Accidents, incidents and emergencies (Regulation 13) Regulation 13 requires that employers prepare for possible accidents, incidents and emergencies involving hazardous substances by: 3 Preparing emergency procedures, including provision of first aid.
Making available technical information on possible accidents and hazards and
bringing it to the attention of the emergency services.
Installing alarms and other warnings and communication systems.
