Final answer:
The items that are inhalation hazards include Carbon monoxide, Chlorine gas, Phosphorus pentachloride, Dinitrogen monoxide, Iodine heptafluoride, and Carbon tetrachloride. Items like OSHA regulations and eye protection, as well as household products such as laundry powder or furniture polish, are not considered inhalation hazards.
Step-by-step explanation:
Among the items listed, the ones that can be considered inhalation hazards are:
- Carbon monoxide (CO) - a colorless, odorless gas produced by the incomplete combustion of fuel such as from gas appliances, which can reduce oxygen delivery to the body's organs and be deadly at high levels.
- Chlorine gas - a toxic respiratory irritant used in industrial applications and household products like bleach, which can be dangerous at high concentrations.
- Phosphorus pentachloride - reacts with moisture to produce hydrochloric acid and phosphoric acids, which are corrosive and can cause respiratory damage.
- Dinitrogen monoxide (laughing gas) - while less toxic, repeated or heavy exposure without appropriate ventilation can lead to health issues.
- Iodine heptafluoride - a corrosive gas that can cause severe burns and is toxic if inhaled.
- Carbon tetrachloride - once used as a dry cleaning solvent and in fire extinguishers, it can cause severe liver damage and serious illness if inhaled over prolonged periods.
OSHA regulations, eye protection, and household products like laundry powder or furniture polish are not inhalation hazards, although they may be related to safety guidelines for handling toxic substances. Secondhand smoke is also a major inhalation hazard as it contains multiple harmful chemicals associated with serious health problems.
