Health Surveillance
Regulations
The Control of Substances Hazardous to Health Regulations
1999 (COSHH) require a risk assessment where employees are using chemicals
or other substances which could put their health at risk (See Occupational
Hygiene). A risk assessment includes the measures to prevent or control
exposure and the procedures for health surveillance.
When is health surveillance required?
Health surveillance is considered appropriate where
the exposure to a substance hazardous to health is such that there is
a reasonable likelihood that the disease or effect may occur under the
particular work conditions of the employee's work, and there are valid
techniques for detecting the adverse health effects at an early stage.
Complying with the Regulations
Decisions on the appropriate form and the level of
the surveillance will require the advice of an occupational health professional.
Industry-specific guidance may be available from trade associations,
including examples of best practice. Health surveillance can be made
a condition of employment and part of the pre-employment health screen,
with repeat testing at recommended intervals during employment.
Health surveillance may be conducted by an occupational
health physician or one of our Occupational Health Nurse advisers. Under
certain regulations the physician has to be an Appointed Doctor for that
workplace and recognized by the Health and Safety Executive. Tests may
include biological monitoring - obtaining blood, urine or breath samples
for analysis in a specialized laboratory - which is another way of checking
on exposure, especially if the hazardous substance is able to be absorbed
through the skin (like many solvents, for example).
Typical examples of health surveillance include:
- Asthma and exposure to respiratory sensitizers
- health questionnaire, spirometry
- Lead - blood testing for lead by Appointed
Doctor
- Asbestos - spirometry and chest X-ray, interview
with Appointed Doctor
- Noise - ear examination and audiometry
- Radiation - interview with Appointed Doctor,
blood test or examination
The OHSC staff are available to provide advice on the
type and frequency of health surveillance your workforce may require.
Investigations such as chest X-rays and audiometry are available at charge
through our OHSC hospitals.
