Protective equipment for the nuclear industry
8 Oct 2013
As the nuclear industry generates electricity, the risks associated with handling nuclear substances and residual nuclear radiation must be taken into consideration.
Hazards and Exposure
Ionisation radiation exposure is the primary hazard when working with nuclear substances, however, residual contamination, through the exposure to particulate dusts, can also pose a serious health risk to those working in the industry.
This exposure can occur, for example, by residual radioactive contaminated particles, such as dusts and Silica, released into the air through the vibrations from the nuclear plant.
Workers can also be exposed through chemical splash and liquid chemicals such as sulphuric acids and sodium hydroxide - all of which prove irritant and corrosive to skin tissue.
Therefore, workers involved in nuclear research and testing, site inspections, reprocessing and general maintenance are also at risk of contamination. Where it is unavoidable for a worker to be exposed to contaminants, it is necessary that contamination is minimised through the correct use of personal protective equipment.
Requirements of Protection
Protective garments are a last line of defence designed to minimise the penetration of liquid chemicals and residual radioactive materials.
These garments are intended for single use; designed to be worn in an affected area and then, promptly removed and disposed of, in order to avoid long term exposure and the contamination of ‘safe’ areas.
These garments should be tested according to EN 1073-2 for protective clothing against radioactive particulates. The test determines the inward leakage and the barrier efficiency of the garment when challenged with a fine salt solution of 0.6 microns.
DuPont Protective Solutions
For effective protection against hazardous chemicals and liquids, DuPont recommends a choice of coveralls. For dry, residual radioactive particle hazards, DuPont Tyvek Classic Plus with socks and thumb loops is recommended. Tested to the highest level of the EN 1073-2 standard, Tyvek Classic Plus coverall offers wearers exceptional levels of protection.
These coveralls are ideal for environments that require effective whole suit protection offered by a Type 4 suit. The over taped seams and the option to seal the zipper area with a self-adhesive flap, are innovative design features that ensure minimal dust penetration. Robust and breathable, Tyvek Classic Plus coveralls balance particulate protection with comfort.
For liquids that have been contaminated by radiation, the ergonomically designed DuPont Tychem C coverall will provide users with comfortable protection against biohazards, inorganic chemicals and hazardous liquids.
While offering Type 3-B, 4, 5 and 6 barrier protection, the coveralls are also hooded for head to toe protection. If additional protection is required, DuPont offers a wide range of accessories made from both Tyvek and Tychem, including protective shoes and aprons.
