Ionising radiation damages the human body by breaking the bonds between atoms in DNA or in other molecules. The "non" in non-ionising radiation makes it sound less harmful -- it carries less energy and therefore cannot break molecular bonds. However, its thermal or photochemical effects can cause damage, in particular to exposed skin and the eyes. The International Agency for Research on Cancer classifies both ionising and optical radiation as group 1 (carcinogenic to humans), while being more precautionary about declaring EMFs as group 2B (possibly carcinogenic) (bit.ly/2zTlLgj).
Although it is easy to avoid the UV from a sunbed, optical radiation sources at work need to be managed. Natural UV from the sun is a hazard for outdoor workers, such as those in construction, forestry and agriculture. Artificial optical radiation arises from lasers used in cutting and drilling, in arc welding and from UV used to sterilise or to cure paint. Infrared radiation is emitted from furnaces.
If you have yet to consider the risk, take a look at the guide to identify whether you have any hazards and find out how to control them.
Although the heating effect of over-exposure to EMFs can cause cataracts, low exposures over time are not thought to add up to a single high exposure, which can occur with chemicals. Like optical radiation, EMFs cannot damage DNA directly.
For susceptible workers, power drills held near the chest could be a problem for people with pacemakers
In the workplace, however, there can be levels of EMFs that can cause harm, particularly to people with powered medical implant devices (such as a pacemaker) or to unborn children. Medical and security equipment, high-voltage power lines and industrial processes that use microwaves, plasma devices or magnetisers are all subject to controls.
The European Directive 2013/35/EU on the minimum requirements regarding the risks from physical agents (electromagnetic fields) sets out exposure limit values to protect workers from adverse health and sensory effects, along with action levels (ALs) to identify when protection or prevention measures should be taken.
Before the Control of Electromagnetic Fields at Work Regulations 2016 implemented 2013/35/EU in the UK, industrial hygienist David Marsh assessed EMF levels at ExxonMobil. What he found was perhaps surprising. "The EMFs from electricity generation plant, transformers and high-power motors were all assessed as producing EMF exposure below the ALs, although potentially above the council-recommended level for susceptible workers. For susceptible workers, power drills held near the chest could be a problem for people with pacemakers, and induction hobs were also a problem if pans didn't completely cover the heating element."
HSE guidance in HSG 281 provides advice on discerning trivial from significant sources of EMFs.
How many stairs are there in your home? Unless you live in a bungalow you probably don’t know the answer to this question. Even if you climb up and walk down them every day it is doubtful that you have ever observed them closely. It probably doesn’t seem important.
The Health and Safety Executive’s (HSE) Workplace Health Expert Committee (WHEC) has called for a greater understanding of the health risks to workers who are exposed to diesel engine exhaust (DEE) and more research into the rate at which diesel engines are being upgraded.
While it is no longer acceptable to assume that all men are stronger than all women, or that people of one colour have different personalities to those of another colour it is, it appears, entirely acceptable to declare that anyone born since 1980 is addicted to social media and will ‘challenge traditional hierarchical HSE systems’, while anyone born before that date is a luddite with no understanding of the modern age, but will be quite happy to toe the line.
A SCUBA equipment supply company has been fined £9,300 and ordered to pay £11,000 costs after providing a diving school with contaminated air that led to children being taken so ill during a training session that one ended up in an induced coma.
