Quick Answer
Protective gear against pumice fallout involves wearing a combination of head, face, and body coverings. A dust mask rated N100 or higher can filter out 99.97% of particles 0.3 microns or larger, including pumice particles. Wearing long-sleeved shirts and pants can also prevent skin exposure.
Choosing the Right Protective Gear
When selecting protective gear against pumice fallout, consider the size of the particles and the duration of exposure. NIOSH-certified dust masks with a P100 rating are suitable for prolonged exposure. However, in extreme conditions, a respirator with a PAPR (Powered Air-Purifying Respirator) can provide better protection. The respirator should be equipped with HEPA filters and a face shield.
Preparing Your Clothing
Protective clothing, such as long-sleeved shirts and pants, should be made of durable, breathable materials like cotton or polyester. Consider wearing a balaclava or ski mask to cover the face and neck area. Long underwear and thermal layers can also provide additional protection against skin exposure. When selecting clothing, prioritize loose-fitting garments to prevent skin irritation and allow for easy movement.
Additional Precautions
In addition to protective gear, take steps to prevent pumice particles from entering your body. Avoid eating, drinking, or applying cosmetics before exposure to prevent ingestion. Keep your hair tied back and wear a hat to prevent pumice particles from settling on your hair. If you’re in a vehicle, close all windows and doors to prevent pumice particles from entering the vehicle. When returning indoors, shower immediately and change into clean clothes to prevent skin irritation and allergic reactions.
