Portwest PS21 is a clear safety goggle designed for suitable chemical-handling tasks involving liquid-droplet hazards. Its lens is cellulose acetate, supported by a soft PVC frame with indirect ventilation and an elastic headband.
Lens and fit
- Clear acetate lens with optical class 1 performance.
- N-rated anti-fog treatment helps maintain visibility as moisture builds up.
- Anti-scratch coating helps reduce surface wear during normal use.
- Flexible frame and elastic strap allow a close fit around the eyes.
- Indirect vents provide airflow without an open, direct ventilation path.
Protection and supply
The manufacturer lists EN 166 low-energy impact protection (F) and liquid-droplet field 3. Chemical suitability depends on the substance, concentration, exposure and compatibility with the lens and frame; this is not a guarantee against every chemical.
Supplied as one pair of clear PS21 goggles. Do not use this model as a sealed gas or fine-dust goggle, or where medium-energy impact protection is required. Inspect and clean the eyewear as directed, and replace it if contaminated, scratched or damaged.
