Hazards/Hazard Recognition
Welding is an extremely hazardous activity requiring skill and focus to complete safely. The Arc Welding Safety Guide is a comprehensive tutorial for Arc Welding and is provided as a reference resource along with the AWS/ANSI Welding Safety Standard PowerPoint and the Safe Working Conditions PowerPoint. Use the Welding Process Hazard Flowchart and map to the Welding Safety Inspection Checklist. Can you think of a non-welding safety standard that could be included in the checklist?
Standard Mapping-Identify overlapping standards for welding safety
Welding is an extremely hazardous activity. There are many organizations who provide overside, guidance, design and safety protocols for welding safety. OSHA incorporates by reference and relies on the welding industry to establish safety standards. In the exercise below map two safety protocols from sections 3, 4, 5, 6, 7 from ANSI Z49.1 for each subpart listed.
| OSHA Subpart | ANSI Z49.1 Safety in Welding, Cutting, Allied Processes-Section number and safety protocol. (2 for each, preferrably different sections) |
|---|---|
| Subpart D – Walking-Working Surfaces | |
| Subpart E – Means of Egress | |
| Subpart G – Occupational Health and Environmental Control | |
| Subpart H- Hazardous Materials | |
| Subpart I – Personal Protective Equipment | |
| Subpart J- General Environmental Controls | |
| Subpart K- Medical and First Aid | |
| Subpart L – Fire Protection | |
| Subpart M – Compressed Gas and Compressed Air Equipment |
|
| Subpart Q- Welding, Cutting, and Brazing | |
| Subpart S – Electrical | |
| Subpart J - Welding and Cutting (1926) |

Welding and Hazardous Materials
Use the following resources to complete the associated activity after viewing video on welding safety.
Case study-Map Corrective Actions
Map the corrective actions identified in the case study to a specific safety standard that is either an engineering, work practice, or PPE control. What were the actual hazards present during or before the event? Cite one or two of the seven common accident causes that contributed to this event.
Case study- Shipyard death
Instructions: As a group review the case study of the Shipyard welder PDF provided. Address in the following recommendations two safety facts from the Whip Around Activity for each recommendation proposed.
Recommendations:
- Employers and employees should assure that equipment is appropriate for the task and maintained to manufacturer’s specifications.
- Daily checks of all hydraulic equipment should include inspection of hydraulic hoses and connections.
- Hydraulic lines should be relocated and protected from physical damage.
- Check all safety equipment and ensure that it is operational, appropriate for the task and that employees know and understand how to use it.
- Employers should maintain a current list and copy of SDS’s for the chemicals in use in the work place, and employees should be appropriately equipped and trained for emergency response.
