Wood Dust - Health Effects - Canadian Centre for Occupational …
2017年8月3日 · Wood dust is created during all stages of wood processing such as sawing, routing, sanding and other operations. Workers can also be exposed when the dust becomes airborne such as when removing dust from furniture, maintenance activities, or when cleaning equipment (e.g., emptying the bag from a dust extraction system or vacuum).
Why is wood dust a health concern? Exposure to wood dust has been associated with health issues due to the natural chemicals in. wood or substances in the wood, such as bacteria, moulds, or fungi. Wood dust is considered carcinogenic to humans (Group 1) according to the International. Agency for Research on Cancer (IARC).

2024年12月12日 · Exposure to wood dust has been associated with health issues due to the natural chemicals or substances in the wood such as bacteria, moulds, and fungi. Wood dust is also associated with toxic effects, irritation of the eyes, nose and throat, dermatitis, and decreased lung capacity and allergic reactions.
CCOHS: Combustible Dust
2024年5月10日 · The dust must be combustible and release enough heat when it burns to sustain the fire. The dust must be capable of being suspended in air. The dust must have a particle size capable of spreading the flame. The concentration of the dust suspension must be within the explosible range. An ignition source must be in contact with the dust suspension.
Health and Safety Report - Volume 2, Issue 10 - October 2004
2023年10月31日 · Some of the health effects of wood dust exposure are due to chemicals in the wood or chemicals created in the wood by bacteria, fungi, or moulds.

The basic requirements for a dust explosion to occur are that combustible dusts are. suspended in air and are ignited. In practice, for a dust explosion to occur, a number of. conditions must be met including: The dust must be combustible and release enough heat when it burns to sustain the fire. The dust must be capable of being suspended in air.
CCOHS: Cleaning with Compressed Air
chip guards or curtains that can deflect flying dust or debris, extension tubes that provide the worker a safer working distance, or ; air guns equipped with injection exhausts and particle collection bags. When using compressed air to clean combustible dusts, potential ignition sources in the dust removal area must be controlled.
