Chemical Material Warehouse at the Rocket Technology Research Center has various flammable and reactive chemicals. One of them is Ammonium Perchlorate, which, at the time of survey, amounts to 21.470.828 g. This condition pose fires and explosions hazard to the chemical material warehouse. To control the risk of fire and explosion hazards in the Chemical Material Warehouse, a fire and explosion risk assessment method is carried out to reduce maximum losses in the event of such hazards. The research methods used are Hazard Identification, Risk Assessment, and Determining Control (HIRADC) and the Dow’s Fire and Explosion Index (F&EI). The results showed four main activities in the Chemical material warehouse with potential risks with 19 low-risk levels and two medium risk levels. After Implementing the HIRADC method and the hierarchy of risk control with the design, administrative, and use of PPE, the level of risk improved from initially medium risk level to all low levels. According to the results of the Dow’s Fire and Explosion Index method, the value of the potential risk of fire and explosion in the Chemical material warehouse of the Rocket Technology Research Center was 122.14. This result was classified as an intermediate hazard level with a radius of exposure in the event of a fire being 31.26 m. The damage factor to be received by the Chemical Raw Materials Warehouse was 79%. To obtain comprehensive measures in the potential for fire and explosion hazards in the Chemical Raw Material Warehouse of the Rocket Technology Research Center, it is recommended that -i.e. HIRADC and Dow’s Fire and Explosion Index are used.
