Safety equipment

Frequently asked questions

• How long does a hard hat last?

  It depends on the manufacturer's instructions and conditions of use; sunlight, chemicals and impact shorten it. A hard hat that has taken an impact must be withdrawn even if it looks undamaged.

• Ear defenders or ear plugs?

  It depends on noise level, exposure duration and how the protection is used. Defenders suit work that requires frequent removal, plugs suit long exposure and hot environments; in both cases the noise reduction value is chosen against measurement.

• Where do you start when selecting personal protective equipment?

  With the risk assessment. Identify the hazard, try to reduce it at source, and treat personal protective equipment as the final layer, chosen against the hazard actually identified.

• When should a helmet be replaced?

  Any helmet that has taken a blow is withdrawn even with no visible damage, because energy absorption is a one-time function. Otherwise the manufacturer's service life applies, since the shell degrades under ultraviolet light.

• What is the difference between FFP2 and FFP3?

  Filtration efficiency and total inward leakage. FFP3 filters a higher proportion of fine particles and is required for the more hazardous dusts; the selection follows the substance, not general preference.

• How often is a harness inspected?

  Visually before every use and formally by a competent person at set intervals. Cut webbing, deformed hardware or any harness that has arrested a fall is withdrawn permanently.
