Health and Safety

Under the Health and Safety at Work etc. Act 1974 and the Management of Health and Safety at Work Regulations 1999, it is necessary to assess the health and safety risks associated with work activities affecting employees and non- employees and take measures to control these risks as far as is reasonably practicable. The following health and safety hazards should be assessed: UV Light Exposure, Fire, Explosion, and Electrical. Details are provided in sections 3.1 to 3.4.

UV light exposure

Safety Classification in accordance with BS EN 62471:2008
Risk Group 3
Warning – UV emitted from this product

Overexposure to UV light can cause adverse health effects, such as erythema (sunburn), photo conjunctivitis and photokeratitis (arc eye) in the short term (acute effects) and can be attributed to premature skin aging, skin cancer, and cataracts as a result of repeated exposure in the long term (chronic effects). The risk for adverse health effects to unprotected skin and eyes from UV light exposure depends on the wavelengths, irradiance levels and personal exposure time. Occupational UV light exposure in Great Britain is subject to the Control of Artificial Optical Radiation at Work Regulations 2010, which was brought into law on 27th April 2010, the European Physical Agents (Artificial Optical Radiation 2006/25/EC) Directive.

This incorporates statutory UV light Exposure Limit Values (ELVs). The Regulations define:

Minimum health and safety requirements for the protection of employees from the risks arising from UV light exposure.
Employers must determine personal UV light exposure levels and compare them with the ELVs as a means of assessing risk and necessary controls.
Employees must not be exposed above the statutory ELVs and must be provided with protection and UV hazard awareness training.

The ELVs define a level of UV light exposure, below which it is believed that nearly all individuals may be repeatedly exposed without adverse health effects. The ELVs – within an 8 hour period per day are as follows:

Maximum permissible effective radiant exposure to
UV light in the spectral region 180nm-400nm (UV-A, UV-B, and UV-C) for unprotected skin and eyes = 30 J/m2 eff
Maximum permissible radiant exposure to
UV light in the spectral region 315nm-400nm (UV-A)
for unprotected eyes = 10,000 J/m2

The ELVs take into account the daily 24-hour light/dark cycle where a cellular repair can take place after the exposure is discontinued. Therefore, in cases where continuous exposure for longer than 8 hours is possible, for example, 10-12 hour extended shifts or even double shifts, special care needs to be taken. Where personal UV light exposure levels comply with the ELVs, the risk can be considered low for the majority of the population and adequately controlled so far as is reasonably practicable. Where personal UV light exposure exceeds the ELVs this constitutes a regulatory offense and additional control measures must be implemented that decrease exposure to below the ELVs.

Control measures

The objective is to ensure that the ELVs for unprotected skin and eyes are not exceeded by any person. This should be achieved by a combination of the following control measures: administrative, engineering, and personal protective equipment. Emphasis should be placed on administrative and engineering control measures to minimize the need for personal protective equipment. All persons who could be exposed to levels of UV light exceeding the ELVs or significant personal exposure must be provided with sufficient information and training to understand the associated risks to their health and precautions which should be taken to adequately manage the risk.

Administrative control measures
Any person who notices any unusual or adverse reaction thought to be due to UV light exposure should not be further exposed until after consulting with a suitably qualified person. It is essential that the following information regarding the UV bulb and UV black filter glass is fully understood and complied with. Compliance with UV light exposure limit values for unprotected skin and eyes defined by The Control of Artificial Optical Radiation at Work Regulations 2010 The ELVs, combined with UV light spectral irradiance measurements for the UV torch have to be used to calculate maximum permissible UV light personal exposure times (MPEs) at defined positions. These are known as hazard values and are provided below.

Hazard Values

Distance from front glass (mm)| Maximum permissible UV light exposure times within an 8 hour period per day

unprotected skin

|

unprotected eye

Only applicable to a UV 5W LED torch, supplied by UV Light Technology Limited.

UV light irradiance measurements used to produce the hazard values above were taken in the center of the beam where UV light irradiance is highest. Therefore, for exposures towards the edges of the beam, an extra safety factor is built in due to reduced UV light irradiance levels.

Where a person is located behind or outside the UV light beam shining directly at a reflective surface, determine the MPEs by using the distance from the front glass to the reflective surface and back to the person. This method will automatically introduce an additional safety margin due to reflective losses. Alternatively, using our UV meter, calculate a reflective loss correction factor to use with the hazard values above. This method is covered during our training course – ‘Safety First with UV Light’. The distance at which the MPE is equal to 8 hours is known as the Hazard Distance (HD), beyond which the exposure limit value cannot be exceeded.

It is necessary for duty holders to limit personal UV light exposure to below MPEs for unprotected skin and eyes. All persons must be aware of and comply with the MPEs for the unprotected skin and eyes were less than 8 hours. If MPs are exceeded then UV light irradiance must be reduced by appropriate control measures. These could include containment, moving further away from the UV light source, reducing exposure time, or as a last resort provision of personal protective equipment (PPE).

Heightened individual photosensitivity
All persons must be aware that their individual susceptibility to UV light exposure can be heightened by photosensitizing agents.
Check that all persons who could be exposed to significant levels of UV light are not unusually photosensitive or exposed to photosensitizing agents, including:

Individuals who are intrinsically photosensitive.
Individuals who are exposed to photosensitizing agents, either ingested, injected, or externally applied.
Very rare cases – aphakics (eye lens removed and not replaced by an artificial lens) or pseudophakic (eye lens replaced with a non UV light absorbing artificial intraocular lens). These persons should be aware that they may not be adequately protected against retinal injury from exposure to UV light within the ELVs.

The ELVs may not be adequate protection for photosensitive individuals and special precautions may be necessary. These individuals should seek medical advice with respect to additional protective measures which may be required before any exposure to UV light.

Heightened collective photosensitivity
Check for any possible photosensitizing effects from contact with chemical compounds in the workplace. Limitation of access – Access to an area where the UV torch is operated should be limited only to persons directly concerned with its use or those necessary.

Warning labels and signs: Should be used to indicate the presence of UV light which could result in persons being exposed to levels of UV light exceeding the ELVs, or significant personal exposure.
Routine maintenance: Essential to ensure optimum performance and minimum risk. The recommended procedures and intervals should be strictly implemented. See section 5.
Engineering control measures: Reduction of reflected UV light – Many surfaces, especially smooth, highly reflective, or light-colored, are good reflectors of UV light. To reduce reflected UV light some surrounding area surfaces could be painted in a dark matt color.
Containment: Indiscriminate emission of UV light into the workplace must not be allowed. The use of screened areas may be appropriate. If used screens must be made of a suitable UV blocking material, well maintained, inspected regularly, and replaced as necessary. Personal protective equipment
Protection of the skin: Areas of skin usually at risk are the backs of the hands, forearms, face, and neck, as other areas are usually covered by clothing. Hands can be protected by wearing gloves and arms can be covered by long sleeves, using a material with low UV light transmission. In general, darker-colored, heavier fabrics with a closed structure offer a higher level of protection than light-colored, lightweight fabrics with an open structure.
The face can be protected by a UV blocking face shield, available from UV Light Technology Limited and this will also provide eye protection.
Particular attention must be paid to prevent gaps in protective clothing that commonly occur around the neck and wrist areas.
Protection of the eyes: We recommend that where personal UV light exposure could be significant, all persons affected should always wear UV blocking spectacles or face shield. These are available from UV Light Technology Limited and will ensure protection against any residual risk.
Fire: Never operate in areas where there is a flammable atmosphere hazard.
Explosion: Never operate in areas where there is an explosive atmosphere hazard.
Electrical
- The battery charger requires a 110-240V/50-60Hz power supply. Electrical equipment is potentially dangerous and may cause death or injury if sufficient precautions are not taken before operation or maintenance. Never operate – if any visible damage to the UV torch, battery charger, cables, or connectors. The battery should only be charged in a dry environment. Before maintenance always disconnect the cable from the battery charger.

Operation

The operation should only be performed by suitably qualified and trained personnel. Handle with care to avoid damage and ensure all packaging material is removed.

Battery installation

a) Unscrew and remove the rear of the UV torch.
b) Insert battery-positive terminal first.
c) Replace the rear cover

Switching on

Before switching on, always check the following. If in any doubt whatsoever do not switch on NEVER operate

a) If there is any visible damage to the UV torch, battery charger, cables, or batteries.
b) Without the necessary control measures in place for protection against exceeding the UV light exposure limit values.

The operator should always point the UV light beam away from their body and never shine directly at anyone’s unprotected skin or eyes. Switch on and off using the power switch on the side of the UV torch. Once switched on it will reach its optimum UV light output almost instantly. Fully charged batteries will provide approximately 90 minutes of run time depending upon the number of on/off switching cycles and the battery capacity. Never put the UV torch down on the front glass when switched on.

Battery charging

Only use battery charger supplied by UV Light Technology Limited.
Allow cooling for 10 minutes. Unscrew and remove the rear of the UV torch.
Remove battery Insert batteries into charger Plug in charger – LEDs should turn ‘red’. If batteries are NOT positioned correctly the LEDs will show ‘green’.
During charging the ‘red’ LEDs will turn ‘amber’ than ‘green’.
When LEDs are ‘green’ the batteries are fully charged. Unplug the charger and remove the batteries. Charging fully flat batteries takes approximately 4 hours

Notes on Charging

a) If the power supply is turned off during charging, the charger will reset and start a new charge cycle when re-instated.
b) Do not leave connected for more than 24 hours.
c) Should the UV torch only be used for short periods (less than 40 minutes) and then returned to charge, we recommend every tenth time the battery is run flat before recharging.
d) Fully discharged batteries should be recharged as soon as possible. Leaving batteries fully discharged for extended periods can permanently damage them.
e) The UV light output will reduce as the battery starts to reach the end of its charge.
f) One battery can be charged at a time if required.
g) Batteries stored for long periods should be discharged and recharged every 6 months.
h) After discharging, batteries should be left to stabilize for 30 minutes before charging.
i) After charging, batteries should be left to stabilize for 30 minutes before use.
j) Battery lifetime is approximately 500 charge cycles.

Disposal of waste batteries, electrical and electronic equipment

The UV torch and any batteries cannot be disposed of with normal waste. They should be taken to an appropriate collection point for the recycling of batteries. electrical and electronic equipment. This will help to conserve natural resources and prevent potential negative consequences for human health and the environment. For more information about where to drop off your batteries, electrical and electronic equipment waste, please contact your local waste disposal authority.

Maintenance

Maintenance of any kind must only be performed by an authorized distributor or suitably qualified and trained personnel. Regular cleaning is recommended to ensure optimum performance. Only use replacement parts supplied by UV Light Technology Limited. UV Light Technology Limited cannot accept any responsibility for damages resulting from improper maintenance, repairs, or use of replacement parts not supplied by UV Light Technology Limited.

Cleaning of the front glass

To ensure optimum performance keep the front glass clean. Wipe over the surface of the front glass with a soft, damp, lint-free cloth or Alcowipe. Never use any soaps, detergents, or abrasive materials.

Cleaning of case threads

It is good practice to wipe over the two threads in the battery end cap and front housing with a clean cloth. This helps maintain good electrical continuity.

UV light irradiance measurement for process control

It is best practice to monitor and record UV light irradiance levels at the working distance to maintain strict process control. This is absolutely essential for some applications to ensure compliance with Standards specifying minimum UV light irradiance or exposure levels. Our UV light meter allows accurate and reproducible UV light irradiance measurements. This should be done at regular intervals, ideally at the start of each period of use.
