How long does Firewatch have to stay after hot work?
Fire watches must continue monitoring the hot work area for at least 30 minutes after completion of the hot work to ensure nothing ignites. This includes all areas that required additional fire watch personnel (e.g., blind compartments and different levels within a space).

A fire watch shall be maintained for at least a half hour after completion of welding or cutting operations to detect and extinguish possible smoldering fires.
Once the work activity has been finished, the permit-to-work must be cancelled in writing by the senior manager and supervisor, and a new assessment undertaken for any new work activities.
Hot work shall not be performed in a confined space until a designated person has tested the atmosphere and determined that it is not hazardous. Fire protection. To the extent possible, hot work shall be performed in designated locations that are free of fire hazards.
Fire watches are required during any hot work activity and for at least 30 minutes after the work is completed in order to reduce the potential for ignitions and large fire losses. There's a single exception: when there are no fire hazards or combustible materials in the hot work area.
OSHA requires fire watch to continue for at least thirty minutes after hot work is complete, while the NFPA recommends at least an hour.
NFPA 101-3.3. 91 Fire Watch.
The assignment of a person or persons to an area for the express purpose of notifying the fire department, the building occupants, or both of an emergency; preventing a fire from occurring; extinguishing small fires; or protecting the public from fire or life safety dangers.
OSHA defines hot work to include riveting, welding, flame cutting, or similar fire- or spark- producing operations. Requirements for hot work are in 29 CFR 1917.152.
At a minimum, your fire prevention plan must include: A list of all major fire hazards, proper handling and storage procedures for hazardous materials, potential ignition sources and their control, and the type of fire protection equipment necessary to control each major hazard.
How long to wait after hot work?
A fire watch should remain on continuous active duty during the hot work and for 60 minutes following the completion of the hot work in order to detect and extinguish any smoldering fires.
Hot work is any work that involves burning, welding, cutting, brazing, soldering, grinding, using fire- or spark-producing tools, or other work that produces a source of ignition.
General precautions
Hot work should only be carried out by trained personnel. Wherever possible items to be the subject of hot work should be removed to a safe area designated for that purpose. In sprinklered premises, hot work should not be carried out when the water supply to the sprinkler system is shut off.
Additional fire watch personnel may be required if the welding is in a location where these sparks or slag may penetrate a wall or floor, or on a raised platform. Because a spark may encounter a combustible object and smolder slowly, the fire watch should continue at least 30 minutes after welding is complete.
Hot work is any activity or process that involves open flames or that generates sparks or heat and includes: Welding and allied processes; heat treating; grinding; thawing pipes; powder-driven fasteners; hot riveting; torch-applied roofing; and any similar applications producing or using sparks, flame or heat.
Examples of hot work include: welding, cutting, grinding, drilling, soldering, brazing, torch-applied roofing, etc.
Fire resistance requirements are either short (30 minutes), medium (60 minutes) or long (120 minutes).
The qualifications you need to get a fire watch job typically include a high school diploma or GED certificate and some specialized training. This training may involve how to monitor smoldering fires, identify a possible fire hazard, or prevent small fires at a welding shop, shipyard, or similar type of workplace.
The PPE required for most hot work includes: Helmet or goggles to protect eyes and face from radiation, debris, sparks and intense light. Flame resistant clothing and apron to protect exposed skin from heat, fires and burns. Ear plugs to protect ears from noise.
Types of Common Firefighter Work Schedules. Fire service work schedules can vary greatly, with the most common schedules being based on 24-hour shifts. However, other schedules may consist of shorter 8 or 12-hour shifts, or even longer 48-hour shifts.
What is the most common firefighter shift?
Firefighters generally work in long shifts that include weekends and holidays. These shifts might differ from one city to another. The two most common types of shifts for firefighters are 24 hours on followed by 48 hours off, or 10- to 12-hour shifts for three to four days in a row.
Eventually the towers would be equipped with radios, and later still a cellular or satellite connection to the Internet, but beyond that the job of fire lookout has changed little since the 1900s. Like the lighthouse keepers of old, there's a certain romance surrounding the fire lookouts.
A Class C fire is the burning of flammable gases, which can be very dangerous and highly explosive. These include gases such as butane and propane in gas canisters, which you'd expect to find in certain building trades. You will also find these with gas camping stoves and gas barbeques.
Standard for the Fire Protection of Information Technology Equipment. This standard covers the requirements for the protection of information technology equipment and information technology equipment areas from fire damage by fire or its associated effects--smoke, corrosion, heat, and water.
This standard presents the minimum fire protection requirements for the construction, installation, maintenance, and use of waste and recyclables storage rooms, containers, handling systems, incinerators, compactors, and linen and laundry handling systems.
| Effective WBGT (°C) | Unacclimatized workers |
|---|---|
| Below 70°F (21°C) | Low risk of heat-related illness |
| 70 to 77°F(21 to 25°C) | Strenuous work possibly unsafe |
| Above 77°F (25°C) | High risk of heat-related illness with strenuous work |
All it takes for skin to blister and burn is a few seconds of incidental contact with a hot surface. The U.S. Occupational Safety and Health Administration (OSHA) sets a limit of a maximum skin temperature of 140°F (60°C) after five seconds of exposure.
There is no requirement for employers to maintain a certain workplace temperature under federal Occupational Safety and Health Administration (OSHA) regulations, nor are there specific OSHA standards for occupational heat exposure.
OSHA requires that all employees be trained to use fire extinguishers. Training is required upon employment and at least annually thereafter. It is recommended the training session cover how to determine when a fire is too big to handle; what type of extinguisher to use; and the PASS system of early-stage firefighting.
portable fire extinguishers, automatic sprinkler systems, and fixed extinguishing systems; detection systems for smoke, heat, or flame; fire alarm systems; and. emergency backup systems and the equipment they support.
What is the one requirement for fire?
Oxygen, heat, and fuel are frequently referred to as the "fire triangle." Add in the fourth element, the chemical reaction, and you actually have a fire "tetrahedron." The important thing to remember is: take any of these four things away, and you will not have a fire or the fire will be extinguished.
Areas can be protected with the use of welding pads, blankets, or curtains, clearing combustibles from a 35-ft (11-m) radius space around the hot work, or moving the hot work to an area free of combustibles.
To prevent heat-related illnesses, they should work shorter workdays in the heat during their first 1-2 weeks. OSHA and NIOSH recommend the "Rule of 20 percent" for building heat tolerance: 20 percent First Day: New workers should work only 20 percent of the normal duration on their first day.
OSHA has no regulations specifically addressing temperature and humidity in an office setting.
The blue, red, and yellow fields (health, flammability, and reactivity) all use a numbering scale ranging from 0 to 4. A value of zero means that the material poses essentially no hazard; a rating of four indicates extreme danger.
Requirements and OSHA Fire Watch Certification
In order to become OSHA-certified as a fire watch, you'll need to complete Safety by Design's fire watch training class and pass an online test. Once you pass the test, you'll receive a card stating that you're a certified fire watch.
“Firewatch” is a single-player game that can be played offline as you follow along a linear storyline that walks you through the plot.
This will return around 30FPS at 720p screen res on low graphics settings, but you can also adjust the settings further to tweak. Minimum RAM requirements are 6 GB system memory. Your graphics card will need to be capable of running DirectX 11.00. In short you need a 13 year old PC for best Firewatch performance.
