Key Hazards
- Worker exposure to unidentified chemicals
- Improper labeling or container transfer
- Mixing incompatible substances
- Inhalation, skin, or eye exposure
- Changing conditions affecting chemical hazards
- Communication failures involving hazardous materials
2–3 Minute Talk Script
Hazard communication is used to help workers recognize chemical hazards, understand exposure risks, and respond safely during routine operations, maintenance activities, cleaning tasks, fueling, and emergency situations.
Many chemical incidents occur because workers assume materials are harmless, fail to read labels, transfer products into unmarked containers, or underestimate how conditions can change during the task.
Chemical hazards may involve inhalation exposure, skin contact, eye injury, fire hazards, toxic reactions, oxygen displacement, or dangerous interactions between incompatible substances.
Outdoor conditions, temperature changes, ventilation differences, confined spaces, weather conditions, and nearby operations can all affect how chemicals behave and how workers are exposed during the shift.
Workers should understand how to identify hazards using labels, pictograms, safety data sheets, warning signage, and workplace communication procedures before handling materials.
Communication between crews becomes especially important when multiple contractors, departments, vehicles, or operations share the same work area. Workers should know what materials are present nearby and how those materials could affect their task.
Chemical containers should remain properly labeled and secured during storage, transport, transfer, and disposal operations. Temporary containers and spray bottles should never contain unidentified materials.
If workers are uncertain about a chemical, exposure condition, compatibility issue, or safe handling procedure, work should stop until the hazard can be identified and communicated clearly.
Safety Reminders
- Read labels and hazard information before using chemicals.
- Keep all containers properly labeled.
- Review safety data sheets when needed.
- Use PPE appropriate for the exposure hazard.
- Watch for changing ventilation or environmental conditions.
- Do not mix chemicals unless approved and understood.
- Stop work if chemical hazards are unclear.
Ask the Crew
- Do workers know what chemicals are present in the work area?
- Could weather, ventilation, or nearby operations change exposure conditions?
- Are all containers properly labeled and secured?
- Would workers know how to respond to an exposure incident?
- Are incompatible materials stored or used near each other?
