TASK: Ventilation cleaning: Specific considerations for U.V. (Ultra violet light)

hoods

What are they ?

UV Hoods such as “Halton’s” MX range claim to keep the hood plenum and duct virtually grease-

free and reduce part of the cooking odours and emissions. Based on the use of Ultraviolet lamps

(UV-C) which neutralises grease vapours and particles.

Effects of UVR on the eyes.

According to the world health organisation responses of the human eye to acute overexposure of

UV radiation include photokeratitis and photoconjunctivitis (inflammation of the cornea and the

conjunctiva, respectively), more commonly known as snow blindness or welder.s flash.

Symptoms range from mild irritation to sever pain and possibly irreversible damage.

There is evidence that chronic exposure to intense levels of solar radiation is a contributory factor in

the development of age-related macular degeneration of the retina and cortical cateracts, both a

cause of blindness.

Team & Surveyor instruction

RULE 1. Always ensure UV light systems are full isolated.

Effects of Ozone poisoning to engineers generated by UV Lamps.

Ozone is widely promoted by ozone generating equipment companies and cleaning services for use

in indoor building environments to deodorize, disinfect, "kill" mold, and for "general health". Ozone

generators are also promoted for use to reduce the level of airborne particles, pollen, animal

dander, and allergens, ostensibly to improve indoor air quality for asthmatics and people with

allergies.

Ozone or O3, or "trioxygen" is a molecule made of three oxygen atoms. In this form, and referred to

as an "allotrope" of oxygen, ozone is an unstable gas - that means it breaks down into oxygen

molecules.

While ozone is helpful in the upper atmosphere (filtering out UV light rays), in lower atmosphere, or

in buildings, it is an air pollutant that is harmful to humans and other animals, and a gas that can

oxidize or "burn" plants or various materials found indoors.

Exposure to a level you can smell or exposure to ozone over long periods at levels greater than

0.05 ppm for 24 hours at a time is likely to be dangerous: [2], [3] Health hazards to humans and

animals occur and can be severe at ozone levels used for indoor cleaning purposes. At least some

people can smell levels of ozone down to 0.05 ppm. This odor-detection level is already half-way to

the recommended limit. If you are generating ozone indoors, even at "low" levels a problem may be

present. People become desensitized to odors in a short time, perhaps 20 minutes. So if you do not

smell it, the ozone level could still be hazardous. Problems include:

•Lung irritation and infection. Breathing pain, coughing, wheezing, difficulty when exercising.

•Permanent lung damage.

•Aggravation of pre-existing asthma

•Increased risk of lung illnesses such as bronchitis and pneumonia

•Reduced breathing capacity

V.H.1

"Ozone is a highly toxic gas but even highly toxic substances can be encountered safely. The main

concern with this material is that concentrations to which people are exposed do not average more

than 0.1 ppm over an 8-hr day, and do not exceed that value by more than a factor of 2 or 3 during

the exposure."

Building and Engineering services ventilation group recommend teams and surveyors follow

the following:-

RULE 2: Switch off UV light and with filters in place team / client to run the fan for 1

hour prior to removal of filters or hatches to allow ozone to dissipate into

atmosphere.

TASK: High Level Cleaning

Using MEWPS Mobile Elevating Platform Work

General

Only operatives who have undertaken an approved IPAF Mobile Elevating Mobile Platform Work

and certificated as competent can undertake this work. Only an IPAF approved technician can plan

work which is involved with working at height and nd must also be able to provide a full risk

assessment and safe method of work before hand. The team leader will check the COSHH

assessment supplied by SHS for the cleaning substances to be used for the task, to ensure that

they will not affect or cause harm to a person working in confined spaces.

Consider: How high does the worker need to reach?

What is the task that needs to be performed?

How close does the worker need to be to the work being performed?

The height required will help in selecting the specific size range of AWP equipment. Be aware that

the height of AWP (aerial working platform) equipment can be expressed in two common ways —

platform height and working height.

1 Operatives to sign in at security reception, receive, read and sign for 'Permit to Work'. The team

leader to perform a toolbox walk through around the workplace and look at what reasonably could

be expected to cause harm. .

2 Team leader to ask team also to assess risks. They may have noticed things that are not

immediately obvious. Consider having someone not associated with the workplace help identify

hazards. A fresh set of eyes can sometimes spot something you’ve overlooked. Note any overhead

obstructions, overhead powerlines, holes, ramps, curbs, others working in same area, debris, other

moving equipment, bumps, wind and weather conditions, inadequate ventilation and inadequate

lighting and assess.

3 Assess the MEWP equipment and ensure familiarity with controls and process. Agree

communication method with team.

4 The operative(s) who will be working on the MEWP to use harnesses.

5 Use the lowest risk option (e.g., select the most appropriate piece of AWP equipment

for the required task). Prevent access to the hazard (e.g., by guarding or using barriers between the

AWP equipment and people/traffic, etc.). Organize work to reduce exposure to the hazard (e.g.,

group tasks and time to reduce exposure or conflicts). Issue personal protective equipment (PPE)

(e.g., hard hats, footwear, goggles, PFPE, etc.). Provide first-aid facilities (e.g., washing facilities for

removal of contamination).

6 (a) Barricade work area to prevent access. (b) Require all workers to wear a hard hat in the work

area. (c) Assign a ground person to warn approaching personnel to take another route if work area

cannot be barricaded.

7 Move debris or material on the floor to allow full access to work area by the AWP equipment.

Remove all debris from the work area.

8 Establishment of clear responsibilities as to who will take what actions and when they will be taken.

Supervision and monitoring to make sure the control measures stay in place at all times.

9 During works ensure a. Establishment of clear responsibilities as to who will take what actions and

when they will be taken. b. Supervision and monitoring to make sure the control measures stay in

place.

10

Please note: AWP equipment have a specifically designed carrying capacity or rated work load

(RWL) specified by the manufacturer. This is a total load, including personnel, tools and materials.

However, you cannot add more personnel beyond the rated number of people, even if

their combined weight is less than the RWL.

11 Specific tools or materials required on the AWP equipment?

a. This will require sufficient rated capacity and the size of the platform to lift all items, in

addition to allowable personnel on the platform.

b.Only properly secured tools and materials, which are evenly distributed and can be safely

handled by workers from the platform, are allowed.

c. If the AWP equipment’s allowable RWL cannot support the required loads referenced,

the task must be reassessed.

12 Note: Always refer to the manufacturer’s operator’s manual to identify the maximum ground

pressure imposed by the AWP equipment as it varies based on the configuration of use.

13 The team leader will then return and sign off the 'Permit to Work' and hand this back into building

security.

14 The team will then leave the site.
