Water Management

Legionella bacteria are widespread in natural water systems, e.g. rivers and ponds. However, the conditions are rarely conducive for people to catch the disease from these sources. Outbreaks of the illness occur from exposure to legionella growing in purpose-built systems where water is maintained at a temperature high enough to encourage growth, e.g. cooling towers, evaporative condensers, hot and cold water systems and spa pools used in all sorts of premises (work and domestic).

It is important to control the risks by introducing measures which do not allow proliferation of the organisms in the water systems and reduce, so far as is reasonably practicable, exposure to water droplets and aerosol.

This will reduce the possibility of creating conditions in which the risk from exposure to legionella bacteria is increased.

GHS Health and Safety consultants can help your business on carrying out water management risk assessments, managing the risk, implementation of control scheme, review of control measures for effective implementation and training, competence of personnel who maintain systems.

Biological Hazards

Biological monitoring is the measurement and assessment of chemicals or their metabolites (substances the body converts the chemical into) in exposed workers. These measurements are made on samples of breath, urine or blood, or any combination of these. Biological monitoring measurements reflect the total uptake of a chemical by an individual by all routes (inhalation, ingestion, through the skin or by a combination of these routes).

Biological monitoring for chemical exposure contributes to the aim of preventing unacceptable health risks by providing information on the control of occupational exposure.

It can give an indication of absorption by all routes of exposure, consequently, it is often used to complement personal air monitoring (which measures the concentration of a chemical in the air in a person’s breathing zone). Therefore, biological monitoring may be particularly useful for those chemicals which are easily absorbed through the skin or taken in by ingestion, or where exposure is controlled by personal protective equipment.

GHS Health and Safety consultants can help your business assess the risks to employees’ health arising from their work with chemicals, advise what precautions they need to take, prevent or control risk, ensure the control measures are properly used and maintained, advise on monitoring the exposure of workers, where necessary, advise on health surveillance, as appropriate and inform, instruct and train employees about the risks and any necessary precautions.
