Emergency preparedness requires equipping workers with knowledge, tools, and rehearsed responses. For chemical spill scenarios, supervisors should ensure every affected worker has access to Safety Data Sheets (SDSs), spill kits (absorbents, neutralizers, PPE), and clearly defined response roles. Training covers recognizing when a spill can be safely managed internally versus when to evacuate and summon external HAZMAT responders. Conducting drills builds confidence and reveals gaps in readiness. Relying solely on supervisors ignores that spills may occur during routine operations when supervisors are absent. Locking SDSs restricts critical hazard information. Deferring entirely to external responders delays containment of small, manageable spills and risks escalation. An STSC integrates spill response into site-specific emergency action plans, coordinates with local emergency services, and documents training and drills. This approach builds resilience, ensures regulatory compliance, and demonstrates leadership in protecting workers, the environment, and the public.
