Hazard Communication (HazCom) Standard pictograms are standardized symbols required by OSHA under the Hazard Communication Standard (HCS), aligned with the Globally Harmonized System (GHS). These pictograms appear on Safety Data Sheets (SDS) and chemical labels to communicate physical, health, and environmental hazards, helping workers quickly identify potential dangers.
The Hazard Communication Standard (HCS) requires pictograms on labels to alert users to potential chemical hazards. Each pictogram is a symbol on a white background with a red border, representing a specific hazard. The selection of pictograms depends on the chemical’s hazard classification, and each appears only once on a label, even if multiple hazards share the same symbol.
OSHA’s HCS aligns with the Globally Harmonized System (GHS) to maintain consistency in chemical hazard labeling. Employers must train workers on these pictograms and their use to contribute to a safer workplace.
OSHA’s Hazard Communication Standard (HCS) includes nine pictograms, each representing specific chemical hazards
Workers must be trained to understand HazCom pictograms and the hazards associated with chemicals. This training helps them read Safety Data Sheets (SDS), follow safe handling procedures, and take necessary precautions to minimize risks. Without proper training, workers may not be aware of potential dangers, increasing the risk of accidents and exposure to harmful substances.
OSHA Training offers online Hazard Communication Pictograms training, allowing workers to learn at their own pace while meeting compliance requirements. This training helps employees identify hazards, read labels and SDS, and understand protective measures when handling hazardous materials.
To comply with OSHA regulations and maintain a safe work environment, employers should:
Hazard Communication pictograms help workers identify chemical hazards and handle materials safely. Clear labeling, accessible Safety Data Sheets (SDS), and proper training help lower the risk of chemical-related injuries and keep workplaces in line with OSHA’s Hazard Communication Standard. Employers should focus on training and hazard awareness to create a safer work environment and protect workers from exposure.
