Explanation:
It is important for a worker to understand the type of hazard that can arise in a workplace whether hazard of contaminants, hazard of confined spaces, nature of work harzards so as follows safe procedures in order to prevent a lifetime injury or death to the worker.
Matching the following hazard with the correct description, we have
1. Usually found in the process of loading, unloading and conveying combustible materials---- Combustible dust concentrations
2. Has approximately the same density as air and can be formed from materials like gas and the decomposition of organic matter-Carbon monoxide
3. Can have sufficient energy to produce sparks and ignite a flammable atmosphere--High charges of static electricity
Can be found in tanks used by the chemical and petroleum industry---Pyrophoric substances
(These are a class of chemical reactions that can form flammable deposits from tanks used in chemical and petroleum industry and can ignite spontaneously upon exposure to the atmospheres examples are ferrous oxide, ferrous sulfate).
