Like other iron(II) salts, iron(II) sulfate is a reducing agent. For example, it reduces nitric acid to nitrogen monoxide and chlorine to chloride: 6 FeSO 4 + 3 H 2 SO 4 + 2 HNO 3 → 3 Fe 2 (SO 4) 3 + 4 H 2 O + 2 NO 6 FeSO 4 + 3 Cl 2 → 2 Fe 2 (SO 4) 3 + 2 FeCl 3. Its mild reducing power is of value in organic synthesis. [44]
Specifically, the objectives of the NASD project are: 1) to provide a national resource for the dissemination of information; 2) to educate workers and managers about occupational hazards associated with agriculture-related injuries, deaths and illnesses; 3) to provide prevention information; 4) to promote the consideration of safety and health ...
The agriculture industry is one of the most dangerous occupations and has led to thousands of deaths due to work-related injuries in the US. In 2011 the fatality rate for farmworkers was 7 times higher than that of all the workers in the private industry, a difference of 24.9 deaths for every 100,000 people as opposed to 3.5 deaths for every 100,000 people in the private industry.

Hazard analysis and critical control points, or HACCP (/ ˈ h æ s ʌ p / [1]), is a systematic preventive approach to food safety from biological, chemical, and physical hazards in production processes that can cause the finished product to be unsafe and designs measures to reduce these risks to a safe level. In this manner, HACCP attempts to ...
Asphyxiant gases in the breathing air are normally not hazardous. Only where elevated concentrations of asphyxiant gases displace the normal oxygen concentration does a hazard exist. Asphyxiant gases are marked SA in the NFPA 704 standard. Examples of hazards are: Environmental gas displacement
When used as part of an aviation hazard analysis, a "Likelihood" is a specific probability. It is the joint probability of a hazard occurring, that hazard causing or contributing to an aircraft accident or incident, and the resulting degree of loss or harm falling within one of the defined severity categories.
Agricultural chemistry often aims at preserving or increasing the fertility of soil with the goals of maintaining or improving the agricultural yield and improving the quality of the crop. Soils are analyzed with attention to the inorganic matter (minerals), which comprise most of the mass of dry soil, and organic matter, which consists of ...
Agricultural spray adjuvants do not reduce the amount of pesticide needed below the recommended use rate on a pesticide label. In fact, it is illegal to use a pesticide in the US outside of the instructions on the label, although FIFRA , the US law governing pesticide use, does allow for the use of pesticides at rates below the label, as long ...
