Hot Work Video-clips

To facilitate risk awareness and training for workers and safety managers, we have developed this educational material that allows an efficient result in a minimum of time.
The videos look "nice", which allows them to bypass some psychological resistance; they are brief and get to the heart, keeping the attention of the viewer.
These pedagogical safety video clips are somehow responses to the interactive assessments of the ""  evaluation application and are also lessons learned in terms of risk prevention.
They were designed based solely on feedback from examples of actual claims. They are concise (30-90 sec.)
The examples that we present may seem exaggerated or out of our imagination. But you can believe, all the examples are taken from real events. We sometimes mixed or transposed some situations, but all is inspired by the feedback. Our video clips focus on the link between cause and effect.

Waste skips
On construction sites, waste skips are a source of many fires. They often have important fuel content and sufficient to transmit the fire to neighboring buildings. Cigarette butts, sparks, oily rags, arson, ... Several sources of ignition are possible. One should be careful and vigilant and those waste should be kept away from buildings.
 Cigarette - V102 
Cigarette butt - Smoking ban
Smoking bans are not always complied with. Smokers do not realize that all butts are small dragons that can ignite long after being thrown away. Smoldering, and protected, the embers can smolder for hours and promote the vaporization of fuel material.
The temperature of the embers being close to the auto-ignition temperature of the smoke, the fire can then start.
Welding on tank
Welding on or around a tank is always dangerous. Even empty, the gas could accumulate to explosive concentrations.
The presence of firemen on the spot does not change anything.
To work safely, it must be degassed and filled with inert gas and flammable gas concentrations should be monitored with a calibrated gas detector. One must also ensure that there is no risk coming from the tanks nearby.

Explosion of gas cylinders on the roof
Storage of gas cylinders on roofs during roofing work should be minimized and the locations indicated on the fire permit.
In case of fire involving gas cylinders, firemen can not intervene or much later. A bottle explosion may spread the fire quickly inside the building.

Wood dust explosion
(and other dust)
Dust explosions can be devastating because they generally spread by a series of small explosions spreading each time more dust in the air and causing larger explosions. Whenever there is accumulation of combustible dust in equipment or in a building, there is a risk of explosion.

Chimneys and gas scrubbers

Industrial chimneys and flue gas treatment equipment may be constructed of plastic or steel coated plastics (FRP). In this case flames or sparks can simply trigger major fires, fanned by the stack effect and very difficult to control.

Fire doors
It is crucial to take care not to prevent the automatic closure of fire doors and repair as needed their devices as soon as possible. In case of fire they can limit the damage and the rapid spread of fire.
Fire walls and fire doors are expensive investments, but they are worthless if the doors are not functional.

Explosive sewer
A sewer is always a risk for work to be performed near or inside. Flammable vapors may be present, due to the fermentation of organic matter inside or because flammable (or just ignitable) liquid spill may cause solvent vapors that are heavier to accumulate.

Work on roofs - skylights
Skylights (sky domes) are made of plastic material and are combustible. If ignited, they may spread the fire by dropping pieces or flaming droplets inside the building. If combustible goods are stored below, fire can spread and destroy the whole building.
That risk should be taken care of by evaluating the risks below and planning emergency actions to take in case of an incident.
Battery Chargers
A battery charger may fail with a short circuit and send flying sparks around. If close to combustible material (wood, cardboard, plastic), the fire can spread quickly. Even if the goods stored were not combustible, they could be destroyed by fire spreading on packaging material (plastic films, pallets). Chargers should always be kept a few meters away, or separated.

 soudure-et-conduction-V111Welding and conduction

Welding on piping or metalic structures is a hazard due to heat conduction and fire spread towards areas hidden from view of the welder. It is important to identify risky places around the work area (insulation material, cables, storage, ...) and keep this risk in mind.

Work on Sandwich Panels
Sandwich Panels are composed of insulation material sandwiched between two steel plates glued on. They may also have a polyester coating. If the insulation is mineral wool, the panel is not combustible, but if the insulation is plastic foam, then it is combustible or even "flammable". Numerous buildings burned down because of this type of panels. One sould be very vigilant and informed before any work.
Fire falling from roof

Roofing work set fire to many activities located below like offices, storage, archives rooms, "tissuthèques" (clothing fabrics archives), hospitals, etc ... Millions of damage and casualties...
A simple seal repair may suffice.
One is never too careful ...

Casting molten bitumen
The molten bitumen, by its temperature, can spread fire to combustible materials such as paper, plastics, paints, insulation, ...
Many fires have occurred this way. If you have below the roof a storage building, the fire can be very violent and in the absence of reliable automatic protection, it will certainly destroy the building in a matter of minutes or an hour.
Electrical cable trays
Cables can burn through the effect of heat generated by an electrical problem, or direct flame contact, or sparks. Dust on electrical cable trays can facilitate inflammation. The fire can spread over long distances horizontally or vertically. Extended downtime can occur. Caulk passages in the walls and cover raceways during construction work.

Bitumen roof fires
The molten bitumen is dangerous because its temperature can ignite combustible materials (paper, cardboard, glue, plastic or gas pipes ...). And once the fire has started on the roof, it is very difficult to stop it because the extinguishing means are limited. It is important to organize your work area, have a good housekeeping, with appropriate distances between hazards.
Storage of gas cylinders
Gas cylinders greatly exacerbate a fire. It is important to store them in limited quantities, especially on roofs, secure them so they do not fall, protect them from knocks, sun, malice, etc...
In case of fire involving exploding bottles, firefighters will lose a lot of time to secure their intervention.

Storage of bottled water
Non-combustible materials can be traps, just because of combustible packaging. Few people are willing to believe that bottled mineral water may spread fire. But it has happened and can happen again. The fire can easily start on plastic film and the plastic of the bottle, then it will run on the plastic surface, on pallets, etc ... When the bottles will fall open and empty, the fire is already several meters away...
Buildings made of Sandwich Panels
There are countless fires refrigerated warehouses, dairies, cheese factories, slaughterhouses, where there is little to burn, except the building itself. The sandwich panels are made of insulating material sandwiched between two steel plates glued on. If the insulation is plastic foam, then it is combustible or even "flammable". A simple electrical fault may suffice. Prudence... Caution... Be Careful...

In April 1996 in Germany, Düsseldorf Airport, renovations were underway at the car park. Welders operating on a parking lot outside were unaware that below them were lounges and boarding terminal. And yet ....
There were dozens of deaths and wounded, dozens...
