Which one of the following best describes toxic substances?
Which one of the following best describes toxic substances? chemicals which have been determined through experience or laboratory analysis to have lethal effects to humans based on dosage criteria.
Which type of chemical is generally considered to be the most hazardous?
Sulfuric Acid. Perhaps the most deadly chemical in the workplace, sulfuric acid is a critical component in the manufacture of most fertilizers, batteries, acids, and metals. Its extremely corrosive nature makes it exceptionally dangerous in its most common concentrations.

What class of hazard is acute toxicity?
GHS Category 5
GHS Category 5 covers chemicals with toxicities expected to fall in the range of oral and dermal LD50 of 2000 mg/kg -5000 mg/kg, or equivalent doses for inhalation toxicity. The basis of classification in both systems is the same: LD/LC50 values or “acute toxicity estimates” of the LD/LC50 .
