Initial Assessment
Now that you understand the scope of the Hazard Communication Standard (HCS) and the responsibilities of employers, the next step is to begin the initial assessment process.
Workers performing an initial assessment of chemicals
Before implementing a hazard communication program, it is essential to determine what chemicals are present in the workplace. The individual conducting this assessment must be knowledgeable about the definitions and characteristics of hazardous substances and chemicals to ensure a thorough and accurate review.
Hazardous Substances and Chemicals
According to OSHA, a substance is defined as a chemical element and its compounds, either in their natural state or obtained through a production process. This includes any additives required to maintain product stability and any impurities resulting from the manufacturing process. However, solvents that can be separated without affecting the substance’s stability or composition are excluded from this definition.
Under the Hazard Communication Standard (HCS), a hazardous chemical is defined as any chemical classified as a physical or health hazard, a simple asphyxiant, a combustible dust, a pyrophoric gas, or any hazard not otherwise classified.
In short, any chemical that poses a potential risk to health or safety due to its properties must be identified and documented during the initial assessment. This ensures all workplace hazards are recognized, communicated, and properly controlled.
