COSHH Assessments – 7 key questions

  In my last post I discussed the main problems that I often encounter with how COSHH assessments are carried out in practice. These were concentrating on the hazards rather than the risks neglecting to include process generated substances concentrating on inhalation exposures and neglecting other routes lack of emphasis on controls failure to considerContinue reading “COSHH Assessments – 7 key questions”

Common problems with COSHH assessments

The Control of Substances Hazardous to Health Regulations (COSHH) are undoubtedly the most important legal requirements for occupational hygienists working in Great Britain. They’ve been around for a long time now – the first version being enacted in 1988 – yet, in my experience, there are still many organisations that haven’t completely got to gripsContinue reading “Common problems with COSHH assessments”

Reconsidering the “hierarchy of control”– Part 1

We normally take a break from running courses over the summer – most people are more interested in enjoying some time off than attending an intensive week of study. But it was back to business as usual last week delivering the BOHS module M103 “Control of hazardous substances” in Chester. I’ll also be running theContinue reading “Reconsidering the “hierarchy of control”– Part 1”

Monitoring skin exposure to chemicals

Inhalation is normally considered to be the main route by which chemicals can enter the body. Most industrial processes where chemicals are used will create airborne dust clouds or lead to the evolution of vapours and gases which are readily inhaled and then absorbed into the bloodstream via the respiratory system. However, in some casesContinue reading “Monitoring skin exposure to chemicals”

Skin Exposure and COSHH Assessments

Recently I’ve been working with a client on a review of their COSHH assessment protocol. Many of their processes involve the handling of lubricants, sealants and adhesives which have a low volatility and present only a minimal risk from inhalation. The main risk of exposure is from skin contact. However we found that their COSHH assessmentContinue reading “Skin Exposure and COSHH Assessments”

Heat stress indices

Assessing the risk from the thermal environment is not easy. One of the main reasons for this is that there are a large number of factors which affect our physiological response to heat. The main ones are Four environmental parameters Air temperature Mean radiant temperature Relative humidity Air velocity And three “human” factors Work rateContinue reading “Heat stress indices”

Diesel exhaust emissions – what to measure?

We recently had a query from a client who’d had a visit from their local Factory Inspector. The client has a large warehouse where they operate diesel powered fork lift trucks. The Inspector asked about the client about their risk assessment of the emissions and then suggested that they arrange to measure the emissions. DieselContinue reading “Diesel exhaust emissions – what to measure?”

Are the Tate’s sunflower seeds a risk to health?

Last week I took a short break in London. On Monday we visited the Tate Modern to see the Gauguin exhibition that had recently opened. On arriving at the gallery we noticed that there was something going on in the Turbine hall. We could see that the floor in a large area of the hallContinue reading “Are the Tate’s sunflower seeds a risk to health?”
