When encountering unfamiliar hazards, what should you do first?

• A. Review SDS, consult safety data for each component, and assess exposure routes before handling
• B. Proceed with handling as usual
• C. Ignore SDS if the chemical is from a familiar supplier
• D. Only wear gloves and continue

Answer: (A)

When you encounter unfamiliar hazards, you must pause and gather information to understand the risks and what controls are needed. Start by checking the Safety Data Sheet for each chemical involved to learn the hazards, including toxicity, flammability, reactivity, and environmental risk, as well as recommended handling, storage, and spill response. The SDS also identifies how exposure can occur—through inhalation, skin contact, eye contact, or ingestion—and it lists the protective measures and controls to use. By combining what the hazards are with how you could be exposed, you can choose appropriate engineering controls (like ventilation), administrative controls, and the right PPE before you handle anything. This approach prevents surprises and reduces risk.

Skipping information, ignoring the SDS, or assuming gloves alone are enough ignores essential safety details and can lead to real harm, since not all hazards are addressed by gloves, and other routes of exposure or reactions may be relevant.
