  • Whoosh Bottle
    Whoosh Bottle Introduction SCIENTIFIC Wow your students with a whoosh! Students will love to see the blue alcohol flame shoot out the mouth of the bottle and watch the dancing flames pulsate in the jug as more air is drawn in. Concepts • Exothermic reactions • Activation energy • Combustion Background Low-boiling alcohols vaporize readily, and when alcohol is placed in a 5-gallon, small-mouthed jug, it forms a volatile mixture with the air. A simple match held by the mouth of the jug provides the activation energy needed for the combustion of the alcohol/air mixture. Only a small amount of alcohol is used and it quickly vaporizes to a heavier-than-air vapor. The alcohol vapor and air are all that remain in the bottle. Alcohol molecules in the vapor phase are farther apart than in the liquid phase and present far more surface area for reaction; therefore the combustion reaction that occurs is very fast. Since the burning is so rapid and occurs in the confined space of a 5-gallon jug with a small neck, the sound produced is very interesting, sounding like a “whoosh.” The equation for the combustion reaction of isopropyl alcohol is as follows, where 1 mole of isopropyl alcohol combines with 4.5 moles of oxygen to produce 3 moles of carbon dioxide and 4 moles of water: 9 (CH3)2CHOH(g) + ⁄2O2(g) → 3CO2(g) + 4H2O(g) ∆H = –1886.6 kJ/mol Materials Isopropyl alcohol, (CH3)2CHOH, 20–30 mL Graduated cylinder, 25-mL Whoosh bottle, plastic jug, 5-gallon Match or wood splint taped to meter stick Fire blanket (highly recommended) Safety shield (highly recommended) Funnel, small Safety Precautions Please read all safety precautions before proceeding with this demonstration.

  • Fire Prevention Program Revised September 2018 Page 1 of 10 Obey All “No Smoking” and “No Open Flame” Signs and Postings
    FIRE PREVENTION & PROTECTION PROGRAM PURPOSE / SCOPE The purpose or goal of the Fire Extinguisher Program is to inform and train employees on preventing fires in the workplace and the proper selection and the use of fire extinguishers in the event of an incipient fire. GENERAL REQUIREMENTS Fire is a common and serious hazard in the construction industry. Each year fires take many lives, cause workers and their families to suffer, and cost millions of dollars. Fire prevention is everyone’s responsibility. Employees must do their part by observing and complying with fire-prevention regulations and procedures. Employees should report any potential fire hazard or condition that could cause a fire to their supervisor immediately. Many potential fire hazards that are commonly found on job sites include gasoline, diesel fuel, oxygen, acetylene and various other building materials. Most fires are caused by a violation of basic fire safety precautions. While proper procedures and training can minimize the chances of an accidental fire, employees must still be prepared to deal with a fire emergency should it occur. In accordance with OSHA standards, our employees must adhere to the following written Fire Prevention and Protection Program. A copy of this program shall be kept at the work place and is available for employee review. Fire extinguishers shall be readily available and located so that personnel do not have to travel more than 75 feet to reach one. On job sites, all Winger Companies, herein referred to as Winger, fire extinguishers SHALL be conspicuously located, readily accessible, and immediately available in the event of a fire for all cutting, welding and grinding operations.

  • 3.9 Fire Safety Equipment Fire Extinguishers Are Very Important
    3.9 Fire Safety Equipment 3.9.1 Fire Extinguishers Fire extinguishers are very important components of laboratory safety. Fire extinguishers are spaced and located as required by current fire codes and standards. Currently the department of Environmental Health, Safety and Risk Management performs monthly inspection and performs required maintenance on all fire extinguishers at Stephen F. Austin State University. Only use a fire extinguisher if the fire is very small and you know how to use the extinguisher safely. If you can’t put out the fire, leave immediately. Make sure you call 911 or fire department even if you think the fire is out. In laboratories, fire extinguishers should be securely located on the wall near an exit. The lab occupant should be aware of the condition of the fire extinguishers by observing them for broken seals, damages, low gauge pressure, or improper mounting. Occupants of laboratories should visually inspect lab fire extinguishers at least monthly. Units that are missing, have broken seals, low pressure or visible damage should be reported to EHSRM immediately for replacement. For fire extinguisher service, requests, training, or any questions call EHSRM at 468- 4532. 3.9.2 Fire Alarms Fire alarms are designed so that all endangered laboratory personnel and building occupants are alerted by an audible warning (in many buildings there is also visual warning). All employees/students should become familiar with the exact location of the fire alarm pull stations nearest to their laboratory. Sprinkler systems, smoke detectors and heat detectors may automatically activate the fire alarm. (This should not be considered a substitute for manual fire alarm activation.) Smoke detectors should never be tampered with and must be regularly checked for viable battery.

  • Paper Mills: Guidance on Fire Risk 2 of 41 Pages Health and Safety Executive
    Health and Safety Executive Paper mills Guidance on fire risk Paper and Board Industry Advisory Committee Health and Safety Executive This is a revision of guidance originally published in 1995. It has been prepared, in consultation with HSE, by the Paper and Board Industry Advisory Committee, which was appointed by the Health and Safety Commission as part of its formal advisory structures. The guidance represents what is considered to be good practice by the members of the Committee. It was agreed by the Commission. Following this guidance is not compulsory and you are free to take other action. But if you do follow this guidance you will normally be doing enough to comply with the law. Health and safety inspectors seek to secure compliance with the law and may refer to this guidance as illustrating good practice. The Regulatory Reform (Fire Safety Order) 2005 During the life of this document, the Regulatory Reform (Fire Safety) Order 2005 will come into force. This will repeal the Fire Precautions Act 1971 and other related legislation under which fire certificates are currently issued. It will also repeal the fire certificates themselves. At this point, general fire precautions then become the responsibility of the duty holder, who has to provide a risk assessment. This determines the general fire precautions needed and fire brigades will continue to enforce general fire precautions under the new legislation. This does not affect the advice given in the following pages except that the reader should bear in mind that the requirement for a paper mill to have a fire certificate prepared by the Fire Authority (mentioned in paragraphs 23, 55, 108, 112, 126 and 134) will be replaced by a specific requirement for the company to perform a risk assessment for fire safety.

  • 2. Whole-House Fire Blanket Protection from Wildland- Urban
    ORIGINAL RESEARCH published: 15 October 2019 doi: 10.3389/fmech.2019.00060 Whole-House Fire Blanket Protection From Wildland-Urban Interface Fires Fumiaki Takahashi* Department of Mechanical and Aerospace Engineering, Case Western Reserve University, Cleveland, OH, United States Each year, fires in the wildland-urban interface (WUI)—the place where homes and wildlands meet or intermingle—have caused significant damage to communities. To contribute to firefighter and public safety by reducing the risk of structure ignition, fire blankets for wrapping a whole house have been investigated in the laboratory and prescribed wildland fires. The fire blankets aim to prevent structure ignition (1) by blocking firebrands to enter homes through vulnerable spots (gutters, eaves, vents, broken windows, and roofs); (2) by keeping homes from making direct contact with flames of surrounding combustibles (vegetation, mulch, etc.); and (3) by reflecting thermal radiation from a large fire within close range (adjacent burning houses or surface-to-crown forest fires) for a sustained period of time. In the laboratory experiment, two-layer thin fabric assemblies were able to block up to 92% of the convective heat and up to 96% of the radiation (with an aluminized surface). A series of proof-of-concept experiments Edited by: were conducted by placing instrumented wooden structures, covered with different fire Michael John Gollner, blankets, in various fires in ascending order of size.

  • Fire Blanket General Directions Your Fire Blanket Is Provided in a Metal Container to House the Blanket When Not Is Use
    Fire Blanket General Directions Your fire blanket is provided in a metal container to house the blanket when not is use. The blanket should be wall-mounted in a central location easily visible to laboratory or chemical SCIENTIFIC storeroom occupants. SAFETYFAX! A fire blanket is a versatile safety aid. It is used primarily as a first aid measure for prevention of shock rather than as a fire extinguisher for burning or smoldering clothes. It is also useful to contain and control chemical spills in the laboratory. The fire blanket is a one-use safety aid. If it is used to extinguish a fire or for spill control, it should be replaced with a new one. Fire The blanket should only be used as a last resort measure to extinguish clothing fires. Fire blankets tend to hold in heat and may increase the severity of a burn. Clothing fires are better extinguished by dropping to the floor and rolling. Ideally, a safety shower is available and used to extinguish clothing fires. The victim may want to use the fire blanket to extinguish a fire involving his person. It would be wise, therefore, to mount the fire blanket on a wall at a height that would easily enable the victim to get the blanket without the need to stand up. Standing up to acquire a fire blanket, while clothing is on fire, should be avoided. If the blanket is mounted at a proper height (perhaps 40 from the floor), a sign (placard) needs to be installed at eye level above the fire blanket to clearly signal its location to room occupants.
