| Work instruction - Flammable material handling |
| Flammable liquids are liquids, liquid mixtures or liquids
with solid particles in solution or suspension (including substances
classified in a different way, based on their hazardous characteristics)
producing flammable vapors at temperatures up to 60.5 °C, in open
vessel tests. |
| Flammable materials may be solid, liquid or gaseous. As they
release oxygen, these materials burn and, under certain circumstances,
may ignite explosively. Flammable materials cause irritations, corrosion,
and noxious and toxic reactions. |
| In accordance with legislation, flammable materials are classified
as follows: |
| t
| Extremely flammable: Substances or liquid mixtures, of which
the flash point (temperature at which the substance may burst into
flames) is below 0 °C and the boiling point is below 35 °C; |
| substances or mixtures that may warm and ignite in the air
at room temperature, without interference from any energy source; |
| substances or solid mixtures that may easily ignite after
a brief contact with an ignition source and that keep burning after
the source is removed; |
| For liquid substances, the flash point is lower than 21 °C.
In contact with water or humid air, extremely flammable gases are
released in dangerous volumes; |
| t
| Flammable: Substances or liquid mixtures, the flash point of
which is equal to or higher than 21 °C and lower than or equal to
55 °C. |
| Handling these materials requires that the following be observed: |
| 1 - | In places of work and storage, floors, desks or racks made
of wood should not be used. The floor must be kept clean. |
| 2 - | Eating, drinking, smoking, and storing food or cigarettes
are prohibited at the workplace and areas close to it. |
| 3 - | The required personal protective equipment, such as safety
goggles, gloves, and, where applicable, aprons and rubber boots, must
be used. |
| 4 - | Wet or excessively dirty clothing must be promptly changed.
This clothing must not be dried. Work clothes - even those slightly
dirty - must be sorted and marked with the following warning before
being sent to laundry: “CLOTHES CONTAMINATED WITH FLAMMABLE MATERIAL”
These clothes must be washed in water. |
| 5 - | Contaminated or wet personal clothes must also be washed
in water at home. |
| 6 - | Flammable materials must not come into contact with organic
substances, such as oil, grease, and solvent, since there is risk
of fire. |
| 7 - | While handling flammable materials, prevent spillage and
dust. In case of leaks, spilt products must not be adsorbed by sawdust
or disposed of in trash cans. |
| 8 - | Solid flammable materials must be swept or wet with absorption
products. These materials must be collected into proper containers
and sent, with indication of content, for disposal. |
| 9 - | In case flammable materials come into contact with the
skin or eyes, wash them promptly with plenty of water (for at least
15 minutes). Then, consult a doctor. Inform about the product affecting
the person. |
