Risk Assessment / Analysis

Employers have a legal duty to carry out an assessment of the risks resulting from work activities to the health and safety of employees and others, such as, the public, volunteers, and external contractors visiting the premises. All risks associated with the workplace must then be controlled.

Potential hazards include:






Explosive Atmospheres


Construction and Demolition

RPS provides a wide range of services for the effective management of Major Accident Hazards including those associated with fire and explosion hazards. The formation of potentially explosive atmospheres in the workplace can be caused by using, storing or generating flammable / explosive gases, mists, vapours or combustible dusts. The potential consequences of igniting explosive atmospheres include loss of life or serious injury, equipment / plant damage, significant financial losses and loss of reputation.
