The appropriate response in this scenario is for the supervisor to stop work until the coating can be identified. This action is crucial for several reasons. First, the safety and health of workers are paramount in any construction operation. If a worker feels ill after exposure to an unknown coating, there is a potential risk for harmful effects from chemical exposure, which could not only affect the affected worker but also others nearby.

By halting work, the supervisor prevents further exposure to potentially hazardous materials. This pause allows for an immediate assessment of the situation, including the identification of the coating's composition. Once the material is identified, appropriate safety precautions can be taken, such as implementing proper ventilation, using personal protective equipment (PPE), or calling in hazardous material specialists, if necessary. The supervisor also ensures that the worker receives medical attention if required.

Continuing work in the presence of an unknown hazard could exacerbate the worker's condition and endanger others, making it imperative to cease operations for safety assessments and mitigation. This approach aligns with best practices for maintaining a safe work environment, emphasizing the importance of proactive health and safety measures in the workplace.
