Ans

6:32 PM Wed 1d the following text and answer the questions: Jobs in agriculture, such as farming and landscaping, including cutting trees and mowing lawns, expose workers to a wide variety of chemical and biological hazards. Chemicals include: ammonia, carbon dioxide, carbon monoxide, hydrogen sulfide, methane, silo gas (nitrogen dioxide), fertilizers (ammonium nitrate) and pesticides. Biological Hazards include: fungi, grain, food, hair/skin, and wastes. Diseases passed from animals to humans are generally called "zoonoses". This means that animals can be infected with a biological hazard, and pass it along to humans. Many types of diseases in animals are not spread to humans. Exposure can be through inhalation, ingestion or absorption through the skin. The health hazard will depend upon the chemical used - some cause lung damage, others cause poisoning. Precautions must be taken when diluting strong concentrations. Use the appropriate personal protective equipment, such as a respirator to prevent inhaling the chemicals, and gloves, clothing and boots that prevent the chemical from touching your skin. At home, read the hazard label, manufacturer's instructions, and make sure that ventilation is adequate. 1. Pick-out three chemical hazards. 2.
