If dust levels cannot be reduced to required limits, which supplementary measure is mandated for workers?

• A. Immediate dismissal of workers
• B. Appropriate PPE must be supplied to the workers
• C. Ignore the regulation
• D. Increase production

Answer: (B)

When dust cannot be brought down to the required limits, the protective approach shifts to providing workers with appropriate PPE. This means supplying respirators or other suitable protective equipment, ensuring it fits correctly, is maintained, and that workers are trained in its use. PPE acts as a supplementary measure to protect employees when it isn’t possible to achieve the limit through engineering or administrative controls alone. The other options don’t reflect safe or legal practice: dismissing workers, ignoring the regulation, or trying to increase production would increase risk and violate obligations.
