Confined Spaces : Guidance For Chipping Work

Working in confined spaces is considered to be a highrisk working activity and when unplanned events occur they often have fatal consequences

Chipping work in confined spaces requires strict adherence to safety guidelines to protect workers from various hazards. Key steps include thorough hazard assessment, ventilation, atmospheric monitoring, proper PPE, and communication, with a focus on emergency procedures and rescue plans

👉Pre-Entry Preparation

1. Confined Space Entry Permit: Obtain a permit from the authorized person, ensuring that all safety requirements are met.
2. Risk Assessment: Conduct a thorough risk assessment to identify potential hazards, such as:
• Atmospheric hazards (e.g., oxygen deficiency, flammable gases)
• Physical hazards (e.g., falling objects, entanglement)
• Health hazards (e.g., dust, noise)
3. Personal Protective Equipment (PPE): Ensure that all personnel entering the confined space wear:
• Hard hat
• Safety glasses
• Earplugs
• Dust mask or respirator
• Steel-toed boots
• Gloves
• Fall protection equipment (if necessary)
• Body Overalls/Cover
4. Tooling and Equipment: Ensure that all tooling and equipment are:
• Suitable for the task
• In good working condition
• Inspected and maintained regularly

👉Chipping Work Guidelines

1. Chipping Technique: Use a controlled chipping technique to minimize dust and debris.
2. Dust Suppression: Use dust suppression methods, such as:
• Water misting
• Dust extraction systems
3. Ventilation: Ensure adequate ventilation to prevent the accumulation of dust and hazardous atmospheres.
4. Noise Control: Use noise control measures, such as:
• Earplugs
• Earmuffs
• Noise-reducing tooling
5. Waste Management: Ensure that all waste materials are properly removed and disposed.

👉Safety Monitoring and Emergency Response

1. Atmospheric Monitoring: Continuously monitor the atmosphere for hazardous gases and oxygen deficiency.
2. Safety Attendant: Station a safety attendant outside the confined space to:
• Monitor the atmosphere
• Provide emergency assistance
• Communicate with personnel inside the confined space
3. Emergency Response Plan: Develop and implement an emergency response plan, including:
• Rescue procedures
• First aid
• Firefighting procedures

👉Post-Entry Procedures

1. Decontamination: Decontaminate all personnel, tooling, and equipment after exiting the confined space.
2. Equipment Inspection: Inspect all equipment and tooling for damage or wear.
