This paper describe how chemical health risk assessment (CHRA) determined the degree of hazard and exposure evaluation in order to identify the risk rating. The purpose of enabling decisions to be made on appropriate control measure, induction, and training of employees, monitoring, and health surveillance activities as may be required to protect the health of employees who may be exposed to chemicals hazardous to health at work. The qualitative methods of CHRA based on SDS (Safety Data Sheet) provides useful information such as the hazard description, the toxicity data, and the risk phrases. Based on these data, the hazard of each chemical can be evaluated and asssigned a hazard rating, these are chloroform, n-hexane, and tetrachloroethylene. The evaluation exposure estimated based on frequency of exposure(F), duration of exposure (D) and magnitude of exposure (M) of chemicals hazardous to health may entering the body through the various root of entry or potential for contact with their eyes, skin, or respiratory. The exposure rating may be assigned the control measures the steps taken to prevent or minimize risk. The risk rating (RR) is evaluated as either significant or not significant. The presence and adequacy of existing control measures showed that risk significant now and already adequately controlled could increase in future (C2) which mean that workers are at risk af adverse health effect since their exposure to the hazardous chemicals not adequately controlled. The control measure by monitoring exposure, control the exhaust system, administrative control, and used appropriate personal protective equipment.
