Chemicals Risk Assessment

risk assessment

The identification of hazards, the evaluation of their risks and the putting in place of control measures to secure the health and safety of employees is a major element for managing health and safety under the Safety, Health and Welfare at Work Act, 2005.

The Chemical Agent Regulations 2001 point out the specific requirements necessary to complete a Chemical Agents risk assessment of the chemical agents used in the work place.  

The Risk Assessment steps:

  1. Identify the chemical hazards.
  2. Consider who might be affected and how they might be harmed.
  3. Evaluate the risks,- what are you doing now and what further precautions are needed?
  4. Document and implement your findings.
  5. Update and review as required.

The first step in risk assessment is to identify the chemical hazards. When recording all potential chemical hazards, look beyond the obvious. As well as considering the use of chemical agents, look at chemicals or substances that may be produced by a process, for example welding fumes etc. Evaluate the correct storage and the quantities of chemicals being stored as well as waste disposal. Consider all materials, preparations/mixtures. Besides chemical agents, consider also, for example, items like glues, materials used by maintenance such as oils, gardening materials, water treatment and cleaning materials.

Check to see whether any of your chemicals are subjected to any Restrictions or Authorisations under the REACH regulation. Your chemical supplier can supply you with this information and must supply you with a safety data sheet, (SDS) which should be provided with each material. The SDS is a primary source of health and safety information. For example the SDS may have your use included in the attached exposure scenarios (ES). It will include occupational exposure limits where they exist or it may have derived no effect levels (DNELs).  (See further information and fact sheet on website on SDSs)

The second step is to consider who (groups of employees) might be affected and how the material/chemical might harm them. Recognise that some  employees may need special consideration, for example, language needs of non-national workers, potential exposure of pregnant employees etc. While the employer is responsible for carrying out the risk assessment, employees should be involved.

The third step is evaluating the risks and deciding on precautions. Write down what precautions you are already taking and apply the principles below in the following order to determine what additional precautions are required:

  • Eliminate the substance or substitute a less hazardous chemical
  • Prevent exposure, for example, by containment and use of local exhaust ventilation (Engineering controls)
  • Organise work to reduce the number of employees that might be exposed. Challenge how processes are carried out. Are there smarter ways of carrying out an activity so that the potential for exposure is eliminated or reduced.
  • As a back-up or final resort, issue personal protective equipment
  • Provide welfare facilities (first-aid and washing facilities to remove contamination)

The fourth step is to document and implement your findings. Write down your findings and discuss them with your employees. A template which can be used for this purpose. Consultation with your employees is necessary at every step and especially when implementing the findings of your chemicals risk assessment. Use this template to draw up an action plan, detailing who is responsible, for what action and when will it be carried out.

As no workplace remains the same, the fifth step is to review your risk assessment  at least once per year, and update if necessary. When changes such as new employees, machinery, equipment or materials occur in the workplace it is necessary to review the risk assessment. Change in work patterns such as overtime or shift work, the needs of pregnant/nursing employees and those with special needs must also be included. When you are finished, check with your chemical supplier to ensure that your use of the chemical is recorded in the Exposure Scenarios part of the Safety Data Sheet which is now required under the REACH Regulation.
