AIR, GAS & ODOUR CONTROL COMBATING DUST & FUMES VODEX WHY RESPIRATORY PROTECTION IS SO IMPORTANT Dust and fumes are a problem with which we are all familiar in our homes, but it can be a much more serious problem in the workplace. The UK Health and Safety Executive (HSE) has already estimated that there are still 1500 new cases of work-related asthma per year. Paul Riddick, Co-Founder and Technical Director at fume and dust extraction specialists Vodex explores how contaminates being produced on a daily basis in the workplace can damage your health and could even prove fatal. Employers have a legal responsibility to protect their employees and the surrounding environment from airborne contaminants, but they also have a social responsibility to look after the health and wellbeing of their employees. Repeated exposure to vapours, fumes and dust is a health hazard. Although vapours are invisible, and many dust particles can 82 PECM Issue 38 be very small (Less than 5 microns) and also invisible to the naked eye, this doesn’t mean the dangers for operators don’t exist. Broadly speaking, dust can be classified into two types: inhalable and respirable dust. Inhalable dust is generally visible to the naked eye under normal light conditions, but it is small enough to get into a person’s nose, throat, and mouth. Respirable dust particles are generally more hazardous, as they are too small for most people to be able to see with the naked eye, so they may be unaware that there is any dust in the environment. These particles are small enough to get right into the smaller tubules of the lungs, and can cause physical blockage or irritation. It can extremely dangerous if the material is toxic or even carcinogenic, as the lungs may be able to absorb it quickly into the bloodstream. Some exposure symptoms can be immediate, such as runny eyes and nose, sore throat and chest pains. Left unchecked, they could lead to Occupational Asthma. This can be a serious condition leading to severe chronic asthma if exposure to a respiratory sensitiser continues. It can take weeks, months or even years to develop, depending on the person and the substance. HOW CAN YOU PROTECT YOURSELF FROM HAZARDOUS FUMES AND DUST AT WORK? Under COSHH Regulations, an employer has a legal responsibility in the UK to carrying out a risk assessment that will highlight any problem areas. The first step to controlling exposure to fumes and dust is to normally examine how they are created in the first place. There may be ways to reduce the volume of fumes or dust that is made or to ensure that less of it becomes airborne.
