Vapour produced by work outside the confined space

This preview shows page 6 - 8 out of 15 pages.

vapour produced by work outside the confined space can also cause fumes to be given off inside, e.g. by welding on the outside; vapour can seep in from surrounding areas while the work is in progress. If the presence of contaminated air is known or suspected, stringent precautions must be taken to protect those inside or about to enter. Ingress of Water, Other Liquids or Free-Flowing Solid Substances Work in a tunnel or duct, or in large chemical or biotechnological plant could result in someone inside finding themselves in water (or another liquid) which is rising dangerously. A similar danger of drowning exists with free-flowing solids like grain, or finely divided chemicals in large storage facilities like a silo or storage bin. Inadvertent operation of machinery could result in a gas or steam being allowed to enter where people are at work. Flammable Substances and Oxygen Enrichment Biological or chemical processes can also cause the oxygen concentration in a confined space to rise. If this is coupled to the presence of flammable or explosive gases (or dust) and a source of ignition, then there is a real risk of a fire or explosion. --------------------------------------------------------------------------------------------------------------------------------------------- UNIVERSITY OF GLASGOW Safety & Environmental Protection Services 6 Telephone: 0141-330-5532 Email: [email protected] NOTE: PRINTED VERSIONS OF THIS DOCUMENT ARE UNCONTROLLED COPIES AND MAY BE OUT OF DATE.

Excessive Heat The presence of elevated (or rising) temperatures will exacerbate the exhausting effects of strenuous work, and increase the possibility of fire or explosion, or increase the generation of toxic fume or vapour. 8. Other Regulatory Requirements The requirements of other Regulations should not be forgotten. They might highlight similar or allied hazards to those outlined above, or place parallel duties on those managing the work. Some of the relevant legal requirements include:- The Control of Substances Hazardous to Health Regulations 2002 The Electricity at Work Regulations 1989 The Provision and Use of Work Equipment Regulations 1992 The Control of Asbestos Regulations 2006 The Noise at Work Regulations 1989 The Construction (Design and Management) Regulations 2007 The Workplace (Health, Safety and Welfare) Regulations1992 The Personal Protective Equipment at Work Regulations 1992. 9. Who Could be at Risk? Of Estates & Buildings staff, those at risk could include any tradesman or manager active in the field such as plumbers, electricians, heating and venting engineers, supervisors, estates development managers, clerk of works etc. In an academic setting, it is possible that geologists, archeologists, engineers, geographers and biologists of many different disciplines, and their students (undergraduate or postgraduate) could be involved in this kind of activity. They may wish to enter a confined space to take samples or check on the progress of an experiment.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
