Before you start working in our institution it is our duty to acquaint you with the basic duties in the field of fire
prevention.
RECORD OF THE ENTRANCE INSTRUCTION IN FIRE PREVENTION
Fire prevention
Knowledge of and compliance with regulations on fire prevention is an integral and constant part of education and
training of each employee irrespective of the work he/she performs.
Basic duties following from the Fire Prevention Act:
1. Every citizen is obliged to behave so as to give no cause for fire that would endanger the life and health of persons
and property, and provide adequate personal and necessary material help in overcoming fires, natural disasters
and other emergencies. Every person noticing a fire is obliged to extinguish it. If the fire cannot be extinguished,
the person is obliged to start alarm (fire regulations and guidelines are posted on the premises) and announce the
fact so that the fire brigade can intervene as soon as possible.
To ensure fire safety, the employees are obliged to:
1. Require from his/her superior instruction about the fire hazard of given operation technology and instruction about
the properties of substances and materials with which he/she works.
2. Take part in schooling and training in fire prevention and pass the required tests. If needed, every employee can
be required to function as a member of a fire guard.
3. Keep the regulations on fire prevention in your work, get acquainted with the fire rules of the workplace, with the
evacuation plan and fire alarm regulations.
4. Get acquainted with the placement and correct use of fire extinguishers (portable fire extinguishers, hydrants) and
other fire prevention appliances in the workplace, be able to use them, be careful not to damage them or use them
for other purposes.
5. Report to the superior or to a person responsible for fire prevention any faults that could endanger safety, and if
needed take part in their elimination.
6. Get acquainted with fire escapes from the workplace.
7. Follow instructions and comply with restrictions on the fire prevention in designated places.
8. Keep the ban on smoking in all workplaces.
9. Avoid working with pressure cylinders without appropriate schooling.
10. Store flammable materials (chemicals, dyes, oils, solvents) only in appropriate vessels and in designated places.
11. Keep the strict ban on using personal electric, gas or other appliances, especially with open fire.
12. Be careful not to perform any repairs of electric installations and appliances, which can be carried out only by
experts.
13. Be careful not to hamper by any material access to electricity switchboards and fire extinguishers.
14. Unplug all electrical appliances from electric current before leaving the workplace! This does not hold for computers
and refrigerators.
The employee most not
1. Intentionally and for no reason send for fire prevention unit or misuse the distress phone line.
2. Perform work that may lead to fire without having the expertise required for such work by special regulations
(welding, flame cutting, electricians´ tests).
3. Damage, misuse or in any other way hamper the use of fire extinguishers or other fire-fighting and fire safety
appliances.
4. Hamper or prevent the use of designated stage areas for fire equipment.
5. Put any material or objects in front of fire prevention devices and fire escapes.

Information about portable fire extinguishers.
Each fire can in the beginning be successfully extinguished by a portable fire extinguisher: operating instructions
are placed on the surface of the extinguisher. All fire extinguishers are actuated only in the close vicinity of the fire.
They are used for extinguishing small and just emerging fires. They contain limited amounts of extinguishing agent
substances. For these reasons it is necessary to carry the portable extinguishers to the close vicinity of the fire and
only then actuate them. To be able to effectively fight fires it is necessary to know the properties of individual types of
fire extinguishers, their actuation, their best use and where they should not be used at all.
Classes of fires, types and check-out of fire extinguishers
Classes of fires and their classification according to the type of the flammable substance are given in the
standard ČSN EN 2 (38 9101) that was completely taken over from ISO 3941and is identical with EN 2:1992.
Class A:
Fires of solid substances, especially organic, whose burning is usually accompanied by glowing – e.g.
wood, paper, plastics, textiles
Class B:
Fires of liquids or substances that turn liquid, e.g. petrol, diesel oil, oils, asphalt, alcohol, paints,
varnishes,
Class C:
Fires of gases - e.g. natural gas, hydrogen, acetylene
Class D:
Fires of metals – e.g. sodium, potassium, magnesium, aluminium.
The jet of the extinguishing agent is to be aimed into the center of the fire, not at the flames and
smoke.
We follow the receding fire by actively advancing in the direction of the wind (wind in the back) to avoid being
endangered by flames and smoke and in order to get a safe view of the fire and its condition.
When the fire emerges we have to discern the degree of risk and the speed of flaring up, and estimate in time
whether we can extinguish the fire on our own and with the firefighting appliances available. If our efforts and
appliances are insufficient we have to call expert aid according to the fire guidelines and not wait until our efforts and
appliances prove to be insufficient.
Portable fire extinguishers hang in visible and readily accessible places.
Classification of fire extinguishers.
According to the extinguishing agent substance the portable fire extinguishers (PFE) can be
classified as:
- water PFE,
- foam PFE,
- dry powder PFE,
- CO2 PFE,
- halone PFE.
In our organization the following fire extinguishers are used in view of the materials and substances
in current use.
