Work involving biological agents

What is the risk?

In spite of their physical and physiological immaturity, young people are no more likely to contract infections from biological agents (micro-organisms) than adults. Like any other person, they may be at greater risk if they suffer from any other disease, are taking medication, or are pregnant.

However, guidance produced by the Advisory Committee on Dangerous Pathogens (ACDP) advises that people aged 18 years and under should not handle animals infected with Hazard Group 4 biological agents, see Working safely with research animals: Management of infection risks.

How to avoid the risk

You must take precautions for all employees regardless of their age or state of health against the risk of:

  • infection at work;
  • acquiring an allergy to certain micro-organisms; and
  • toxicity (eg C botulinum).

Follow a risk assessment in line with the requirements of the COSHH Regulations and the ACDP Guidance. (Biological Agents: Managing the risks guidance)

Control measures required can often be as simple as maintaining high hygiene standards ie hand washing and use of gloves.

Where available, you should offer employees vaccination as a supplement to procedural or physical controls (see Schedule 3 of the COSHH Approved Code of Practice).
