How is chemistry used in firefighting Chemistry is at the heart of combustion. Indeed, combustion - fire - is applied chemistry, chemistry in action. That's why some knowledge of chemistry is important in fighting fires. The firefighter employs strategy and tactics to contain and extinguish fires that are all directly or indirectly based on a knowledge of the chemistry of fire. The fire triangle, for example, is basic chemistry.
Heat Detectors: Heat detectors, are designed to trigger when heat causes a rapid change in temperature. Heat detectors are best situated in confined spaces and are located on the ceiling. Smoke Detection: Smoke detectors like smoke alarms detect fire far more rapidly than heat detectors. Smoke detectors are better suited to large open spaces as smoke doesn’t disperse as quickly as heat. Flame Detections: Flame detectors respond to radiant energy, from sources such as glowing embers, coals and also flames.
Exhaust hoses should be used because one of the exhaust gases is deadly in high concentration. This gas is _________. 7. The process of combustion occurring without an open flame is called ___________. 8.
Once fire has started, the first opportunity to reduce its impact comes in the design of burnable items, i.e., the choice of materials and products and their environments. C. Active force protection systems provide the next opportunity. Automatic detection systems will tend to activate first, followed by automatic sprinklers or other automatic suppression systems, although this will vary depending on the design of the detection and suppression systems. D. Passive protection is designed to confine fire and smoke in zones, a concept called compartmentation. Special attention is given to protection of the building’s structural integrity and the spaces through which occupants will move to safety.
Unit 8 Contribute to health and safety in health and social care 1) Legislation that relates to health and safety includes, amongst others, the Health and Safety at work Act 1974, Management of Health and Safety at Work Regulations 1999 and Health and Safety (Enforcing Authority) Regulations 1998, RIDDOR, COSHH, Manual handling Operations Regulations 1992. We also have policy and procedures within our own work place for example the use of Oxygen policy for when a customer has been given oxygen within their home environment the policy outlines the risk of smoking, open fires and the storage off the unit or canisters they have. If they live in a residential home we would let the co-ordinator know that oxygen is on the premises so they then can put in place their own policy and procedures that they may have. The general roles and responsibilities of health and safety policies and procedures agreed with my organisation for colleagues include: Having a personal and collective responsibility to promote safe working practices and maintain a healthy, safe and secure workplace. Have a responsibility to ensure that they have an awareness of and comply with the organisations health and safety policy.
Industry Heat Exposure (Allowable Limits) Standards Heat Exposure Standards are a set of guidelines to prevent the risk of overheating and heat stress at work spaces. According to the Heat Stress in the Workplace. What You Need to Know as an Employer brochure issued by Health and Safety Executive in August 2003, “Heat stress occurs when the body’s means of controlling its internal temperature starts to fail. As well as air temperature, factors such as work rate, humidity and clothing worn while working may lead to heat stress.” (http://www.hse.gov.uk/pubns/geis1.PDF). The standards are meant to be applied in many workspace situations and industries.
Describe how you should evacuate in case of an accident. d. Label the fire exits in the diagram and add the evacuation route to your picture (this should be posted in your room). Laboratory Safety Diagram 2. Biohazard materials are disposed of in biohazard bags when you are finished working with them. a.
Airborne Precautions Airborne precautions are required to protect against airborne transmission of infectious agents. Diseases requiring airborne precautions include, but are not limited to: Measles, Severe Acute Respiratory Syndrome (SARS), Varicella (chickenpox), and Mycobacterium tuberculosis. Preventing airborne transmission requires personal respiratory protection and special ventilation and air handling Airborne precautions include: * Standard Precautions * Personal respiratory protection * N95 respirator Prior fit-testing that must be repeated annually and fit-check / seal-check prior to each use. or * Powered Air-Purifying Respirator (PAPR) * PAPR More information about PAPR respirators. * Airborne Infection Isolation Room (AIIR) * At a minimum, AIIR rooms must: * Provide negative pressure room with a minimum of 6 air exchanges per hour * Exhaust directly to the outside or through HEPA (High Efficiency Particulate Air) filtration * Contact Precautions * In addition to standard precaution, use Contact Precautions in the care of patients known or suspected to have a serious illness easily transmitted by direct patient contact or by indirect contact with items in the patient’s environment.
Characteristic waste is broken up into four categories: ignitability, corrosivity, reactivity and toxicity. Characteristic waste describes waste that, “poses a sufficient threat to merit regulation as hazardous” [2] (p.1). Ignitability is described as liquids that have a flash point below 60 oC [4]. They can cause fire through specific conditions and are ignitable compressed gases and oxidizers [4]. Anything characterized as ignitability is given the waste class code of D001.
Ensure A Safe Workplace The hazard identification process is designed to identify all the possible situations where people may possibly be exposed to injury, illness and disease arising from all sources including the above. Prior to the introduction of any plant, substances, processes or work practices in the workplace, it is essential for the hazard identification process to be carried out to identify whether there is any potential for injury, illness or disease associated with such introduction. This essay will analysis a case study in ABC Chemical about the hazard identification process. Legislation The Occupational Health and Safety (Hazardous Substances) Regulations 1999 require employers to ensure that: * an assessment is made to determine whether there is any risk (likelihood of injury, illness or disease) associated with the use of a hazardous substance at the workplace; and * any risk is eliminated, or if that is not practicable, reduced so far as is practicable. The Occupational Health and Safety (Noise) Regulations 2004 require employers to ensure that: * any risk to employees from exposure to noise is identified; and * employees' exposure to noise is controlled so as to minimise risk to health and safety.
