Control measures
- use Local Exhaust Ventilation (LEV) to extract the dust close to the source (see photograph above, which shows a smoke test being used to check an LEV’s ability to extract such dust)
- clean work areas using vacuum cleaners rather than brushing.
- alternatively, dampen areas with water before dust collection.
What precautions must be taken when working with a chemical that releases toxic vapors?
Prevent the release of toxic vapours, dusts, mists or gases into the workplace air. Wear appropriate personal protective equipment (if necessary) to avoid exposure (eye, respiratory or skin) or contact with contaminated equipment/surfaces. Be aware of the typical symptoms of poisoning and first aid procedures.
How can respiratory hazards be prevented?
The filtering facepiece respirator, also known as the dust mask, is the most basic form of respiratory protection. It provides the least amount of protection of all the respirators and protects employees from particulate exposures and nuisance dusts.
What happens if you breathe in a lot of dust?
You may not think it’s a big deal when you breathe in dust, but for some people, it could bring on a lung disease called hypersensitivity pneumonitis. It’s an allergic reaction to particles in the dust, and it can cause symptoms like coughing and shortness of breath.
What is an example of a toxic material?
There are a number of very toxic materials that may be used in workplaces. Some examples include carbon monoxide, hydrogen sulfide, chlorine and sodium cyanide. Extreme care and caution must be used if there is potential for any form of exposure to very toxic materials.
What is an effective method to protect yourself from chemical exposures?
The three most effective ways to control and prevent chemical exposure at the source are substitution, mechanization or engineering controls, and administrative and work practices controls.
Can a lot of dust make you sick?
What are the three major types of potentially toxic agents?
There are three major types of potentially toxic agents.
- Carcinogens are chemicals, types of radiation, or certain viruses that can cause or promote cancer.
- Mutagens are chemicals or forms of radiation that cause mutations, or changes, in the DNA molecules found in cells, or that increase the frequency of such changes.
