What are hazardous dusts?

Hazardous dusts (health endangering) are defined as hazardous to health if inhaled, ingested or in contact with the skin. Hazardous dusts include asbestos, finely divided silica, carcinogens and highly active pharmaceutical products. 

What is a Type H vacuum cleaner?

A Type H Vacuum Cleaner is needed to safely and effectively pick up hazardous dusts.

The Kerstar range of Type H vacuum cleaners are fitted with three stages of filtration on the negative pressure side of the motor (that is before the motor, so that the motor always receives clean filtered air).

1st Stage: Sealable Disposable Microfibre Bag

2nd Stage: High Efficiency Filter Assembly using a filter medium that is specially designed as a pre-filter material for HEPA filters

3rd Stage: is an oversized HEPA (High Efficiency Particulate Air) cartridge filter (also known as the Absolute or Essential Filter) housed in a sturdy replaceable module.

Every Type H vacuum cleaner is individually Dispersed Oil Particulate (DOP) tested on calibrated test equipment to achieve a filtration efficiency of greater than 99.995%.

Health & Safety regulations

All markets have their own regulations to govern health and safety in the workplace. For example, in the UK all businesses regardless of size are bound by the Control of Substances Hazardous to Health (COSHH) Regulations 2002. COSHH is designed to minimise exposure and protect workers’ health. Please check out the regulations in your own country.

The nature of the dust and debris being collected by Type H vacuum cleaners means extra care and special precautions may need to be taken.
