RESPIRATORY PROTECTIVE EQUIPMENT (RPE) FIT TESTING

RESPIRATORY PROTECTIVE EQUIPMENT (RPE) FIT TESTING

An inadequate fit will significantly reduce the protection provided by the RPE and may lead to serious immediate and long-term health problems.

The performance of all RPE face pieces, whether operating by negative pressure, power assistance or compressed air, relies heavily on the quality of fit of the face piece to the wearer’s face.

RPE testing

Fit Testing is available on-site or at our laboratory for full-face, half-face, ori-nasal and P3 disposable masks. Additionally we offer training in the correct use of respiratory protective equipment (RPE).

The Health and Safety at Work Act 1974 requires all employers to take satisfactory precautions to protect their employees in the workplace.

Under the revised Health and Safety Executive Legislation (2002), fit test reports should be available for all employees who wear respiratory protective equipment (RPE) incorporating tight fitting face pieces. Fit test records should be retained by the employer and be available for inspection upon request.

Regulation 11 of the control of asbestos regulations (2012) states that fit testing of face pieces must be pertained for tight fitting face pieces. Repeat testing is required when changing size or model of RPE, or with significant changes in facial characteristics of the wearer. The HSE recommend that fit retesting be carried out on a regular basis, especially for workers involved in licensed asbestos removals.

One of our occupation team was recently up in Cardiff at the Brunel House

One of our occupation team was recently up in Cardiff at the Brunel House. We attended site following the cleanup of a sewage leak that spread throughout the bottom basement floor. Whilst on site we took bio-aerosols within each of the separate rooms where the leak spread to make sure all airborne bacteria had also been removed from the cleaning.

Emissions testing

Written by

We are currently helping a local University test the efficiency of their emission filters to restrict vehicle fumes entering the building and thus in the air circulation throughout the rooms. We have set up tubes to test sulphur dioxide and nitrogen dioxide to test the concentration of the gases from the ventilation, and also tested for particulates in the air. This is an ongoing project with every building tested either before or after the filters have been changed.

Colourimetric tests

Written by

Alkalinity, also known as acid capacity, is one of many colourimetric tests that Envirochem offers. This measures how much acid the solution can absorb before its pH is changed. This test is used in concrete water and waste water. Biological organisms required for wastewater treatment are most effective at a neutral to slightly alkaline pH (7-8). In order to maintain this pH the wastewater needs sufficient alkalinity to neutralise acids produced by the biological organisms.

Lead in Paint Survey for Homebuyers

Written by

Envirochem were recently approached by an individual client who requested a Lead in paint survey be carried out on a property they wanted to purchase.

An individual client used Envirochems website to contact us and to request a Lead in paint survey on a property they wanted to purchase in Reigate. The client had a home buyers carried out on the property they wanted to purchase and it was highlighted that due to the age of the property, Lead paint may have been used in the decoration of the building. With concerns of the Lead content in paint and with a young child, the client wanted the paint from various areas of the building checked before remediation works are carried out within the property. With the aid of the client, sampling areas were agreed and scrapings from various surfaces were taken of the paint, labelled and bagged and taken back to the laboratory from analysis. Paint sampled are digested in Aqua Regia using microwave digestion and subsequently analysed by Inductively Coupled Plasma Optical Emission Spectrophotometry (ICP-OES) using our UKAS accredited procedure (please note, Envirochem are only accredited for the analysis of Lead in paint and not the sampling of lead in paint). A report was subsequently produced to report the results.

Envirochem can carry out a variety of paint analysis for individual homebuyers and other clients. For this serives and all our other services please call us on 01329 287 777 or fill in the form below.

Noise at a Waste Recycling Depot

Written by

Envirochem were recently approached by one of their clients to carry out a noise survey at a waste recycling depot in Reading

Envirochem travelled to Reading to carry out a Noise survey at a waste recycling depot in Reading. The waste recycling depot had a variety of areas in which noise could potentially become a problem for employees exposed to levels of noise above that of 80dB being the lower exposure action level as stated in the Noise at Work Regulations 2005. Using a Cassella CEL 620B Class I integrating sound meter with octave band filter and with the guidance of the client, noise samples were taken from nine different areas of the depot to take into account the different activities which take place in the yard and in the indoor areas. The noise levels were on a whole below the action level in the outdoor areas within the yard but exceeded this level when the samples were taken inside. This would suggest that employees working in the internal areas should be provided with hearing protection and this area should be classed as a hearing protection zone.

Envirochem can carry out a variety of occupational hygiene monitoring services for individual clients and businesses for noise and any other health, safety and environmental need. If you require any of our chemical analysis services, occupational hygiene services, asbestos or microbiological services, please fill out the form below or give us a call on 01329 287 777.

Building Cladding testing services

Written by

Envirochem has had two separate enquiries about testing the core material in aluminium composite panels. Two sheets of aluminium sandwich a non-metal core; these panels are often used for cladding on the outside of buildings. In order to determine whether the core was polyethylene or not, we ran a comparison scan with a known sample of polyethylene on our GC-MS (gas chromatography linked mass spectrometry). This allowed us to look for marker peaks like ethane, which is a good indicator for polyethylene.

Identification of unlabelled substances to determine what they contain

Written by

At Envirochem, we often receive unusual samples for analysis. One recent example of this was a set of around 60 bottles collected by us from a residential property. The bottles had been found during a house clearance as the previous owner had owned his own printing company. We created an inventory of the compounds in order to request a quote from a disposal company that we work with. We plan to analyse any unlabelled substances to determine what they are.

During the inventory, we found two bottles containing mercury. Mercury is a very interesting element. It is the only metal to be liquid at room temperature and has a very high surface tension, so forms rounded beads of liquid.

We test many different types of samples for mercury including soil, water, leachates (as part of the WAC testing suite of analysis) and air (mercury fumes or dust).

    present within the sample

Analysis will enable the end user to:

  • Assist with the determination
    of the Waste Acceptance
    Criteria
  • Identify potential for asbestos
    exposure adjacent
    to contaminated land
  •  Identify the total percentage
    of asbestos present in
