- Safety Glasses: Use goggles or safety glasses to protect your eyes from debris.
- Protective Clothing: Wear flame-resistant and protective clothing to guard against potential risks.

Risk Assessment

Conduct a thorough risk assessment:
- Potential Hazards: Identify and document potential hazards, including temperature, pressure, and material risks.
- Emergency Procedures: Have a detailed emergency response plan in place for immediate actions in case of unexpected incidents.

Emergency Response Plan

Develop a comprehensive emergency response plan:
- First Aid: Ensure first aid kits are readily available and accessible.
- Evacuation Routes: Clearly marked evacuation routes should be available for quick and safe exit.

Team Training

Train all team members on safety protocols and procedures:
- Regular Training: Conduct regular training sessions to ensure all personnel are up-to-date on the latest safety measures.
- First Aid Training: Equip team members with first aid training to provide immediate assistance in case of injuries.
