3. Maintain exposure controls
You must make sure any controls you have to protect your workers from health risks from welding fume remain effective:
- Follow instructions on how to use equipment
- Keep equipment in working order
- If equipment is faulty, repair it straight away
- Each day look for signs of damage
- Get a competent ventilation engineer to thoroughly test and examine the LEV system and its performance at least every 14 months
- Keep records of all examinations and tests for at least 5 years
- Review records – failure patterns show where you need to do preventive maintenance
- Review your controls when anything changes in your workplace
