The most common exposure route to chemicals in the work environment is through inhalation. Gas, vapour, mist, dust, fumes, and smoke can all be inhaled. Those with occupations involving physical work may inhale higher levels of chemicals if working in an area with contaminated air.
Is chemical a biological agent?
Chemical agents are hazardous substances that usually would make you sick immediately. Examples of chemical agents include mustard gas, cyanide, and sarin. Biological agents are usually viruses or bacteria which may take several days to make you sick once you are infected.
Which is an example of a hazardous chemical agent?
Some examples of chemical agents include phosgene (a choking agent or lung irritant), hydrogen cyanide (a blood gas), dibenzoxazepine (a type of tear gas), and sarin (a type of nerve gas).
What are the 4 types of chemical hazards?
- Asphyxiant Chemical Examples: Carbon monoxide and cyanide.
- Corrosive Chemical Examples: Sulfuric acid and sodium hydroxide.
- Irritant Causing Chemical Examples: nickel chloride and chromic acid.
- Allergen Causing Chemical Examples: Chlorine and alkalis.
What type of hazard are vapors fumes?
Airborne chemical hazards exist as concentrations of mists, vapors, gases, fumes, or solids. Some are toxic through inhalation and some of them irritate the skin on contact; some can be toxic by absorption through the skin or through ingestion, and some are corrosive to living tissue.
What are examples of fumes?
An example of fume is for a grill to produce smoke. An example of fume is to show how annoyed you are at someone for something they said. The definition of a fume is smoke or gas, or something that is not real. An example of a fume is smoke from a barbecue.
What are the 5 biological agents?
They include bacteria, viruses, fungi (including yeasts and moulds) and internal human parasites (endoparasites). The majority of these agents are harmless however some may have potential to cause ill health.
Which of the following is not a biological agent?
D) Pollen is a fine to coarse, powdery substance that contains pollen grains that are male microgametophytes of seed plants. It is not a biological agent of a disease. Therefore, the correct answer is option ‘C’ i.e, pollen.
What is considered a biological agent?
Biological agents include bacteria, viruses, fungi, other microorganisms and their associated toxins. They have the ability to adversely affect human health in a variety of ways, ranging from relatively mild, allergic reactions to serious medical conditions—even death.
What are examples of a chemical agent?
Chemicals agents or chemicals are present in every workplace. For example, inks, toners, adhesives, paints, oils, lubricants, hair dye, laboratory reagents, welding fume, hazardous medicinal products and cleaning fluids are all examples of chemicals.
What are the examples of biological hazard?
- Antibiotic/Antimicrobial Resistance in Bacteria and Organisms.
- Avian Influenza.
- Bed Bugs in the Workplace.
- Clostridium Difficile.
- Common Cold.
- Flood Clean-up.
- HIV/AIDS (11)
Which is not considered a chemical substance?
What Is Not a Chemical? If anything made of matter is made up of chemicals, which means that only phenomena that aren’t made of matter are not chemicals: Energy is not a chemical. Light, heat, and sound are not chemicals—nor are thoughts, dreams, gravity, or magnetism.
What are the 5 chemical hazards?
- Carbon Monoxide.
- Hydrochloric Acid (HCl)
- Sulfuric Acid.

Reactivity is not a chemically related health hazard.
What is a biological hazard in the workplace?
Biological hazards, also known as biohazards, are organic substances that pose a threat to the health of humans and other living organisms. Generally speaking, biological hazards include pathogenic micro-organisms, viruses, toxins (from biological sources), spores, fungi and bio- active substances.
What’s the difference between fumes and vapors?
Some liquids or solids have an associated gaseous phase which is called a vapour. Smoke is a fine solid formed by incomplete burning. Fumes are fine airborne particles produced when a solid vapourises and condenses, eg during welding.
Are vapors and fumes the same?
A fume or fumes refers to vapors (gases), dusts and/or smoke given off by a substance as a result of a chemical transformation such as reaction, heating, explosion or detonation. “Fumes” generally conveys the idea that the cloud is an irritating, hazardous and/or toxic substance.
Are gases and fumes the same thing?
Fume – Solid particles generated by condensation from the gaseous state, generally after volatilization from melted substance (e.g. welding), and often accompanied by a chemical reaction such as oxidation. Gases and vapours are not fumes. Gas – A substance that is in the gaseous state at room temperature and pressure.
How do you describe fumes?
Fumes are vapors produced when a metal is heated above its boiling point. The fumes consist of extremely fine particles that remain suspended in the air for a brief amount of time. Fumes are hazardous substances and inhaling them can result in irritation and a number of chronic health conditions.
What is mean by fumes?
1a : a smoke, vapor, or gas especially when irritating or offensive engine exhaust fumes. b : an often noxious suspension of particles in a gas (such as air) 2 : something (such as an emotion) that impairs one’s reasoning sometimes his head gets a little hot with the fumes of patriotism— Matthew Arnold.
What are fumes made of?
Fumes are formed when a metal is heated above its boiling point and its vapours condense into very fine, particles (solid particulates).
What is the approved list of biological agents?
The Approved List is the list of classifications of biological agents approved by HSE for this purpose. Biological agents are bacteria, viruses, parasites and fungi which can cause harm to human health, usually due to infection (some are toxic or can cause an allergy).
Is dust a biological agent?
Biological agents can cause three types of disease: infections caused by parasites, viruses or bacteria; allergies initiated by exposure to mould, organic dust like flour dust and animal dander, enzymes and mites; and. poisoning or toxic effects.
What are the 6 category A biological agents?
- Anthrax (Bacillus anthracis)
- Botulism (Clostridium botulinum toxin)
- Plague (Yersinia pestis)
- Smallpox (variola major)
- Tularemia (Francisella tularensis)
- Viral hemorrhagic fevers (filoviruses [e.g., Ebola, Marburg] and arenaviruses [e.g., Lassa, Machupo])
How many biological agents are there?
A biological agent is an infectious disease. They can be naturally occurring or be used in biological warfare. There are more than 1200 different kinds of biological agents, some of which can be used as biological weapons.
