Environment, health and safety (EHS) (or health, safety and environment –HSE–, or safety, health and environment –SHE–) is an interdisciplinary field focused on the study and implementation of practical aspects environmental protection and safeguard of people's health and safety, especially in an occupational context.

In 2011, the WHO/International Agency for Research on Cancer (IARC) has classified radio frequency electromagnetic fields as possibly carcinogenic to humans (Group 2B), based on an increased risk for glioma and acoustic neuroma associated with wireless phone use. The group responsible for the classification did not quantify the risk.
Unlike its counterpart, the Occupational Safety and Health Administration, NIOSH's authority under the Occupational Safety and Health Act [29 CFR § 671] is to "develop recommendations for health and safety standards", to "develop information on safe levels of exposure to toxic materials and harmful physical agents and substances", and to "conduct research on new safety and health problems".

Some medical peer reviewed journal articles refer to ELF in the context of "extremely low frequency (ELF) magnetic fields (MF)" with frequencies of 50 Hz [15] and 50–80 Hz. [16] United States Government agencies, such as NASA, describe ELF as non-ionizing radiation with frequencies between 0 and 300 Hz. [ 14 ]
A simple element of risk quantification is often introduced in the form of a risk matrix, as in preliminary hazard analysis (PreHA). The selection of the methodology to be used depends on a number of factors, including the complexity of the process, the length of time a process has been in operation and if a PHA has been conducted on the ...
A hazard and operability study (HAZOP) is a structured and systematic examination of a complex system, usually a process facility, in order to identify hazards to personnel, equipment or the environment, as well as operability problems that could affect operations efficiency.
