2. Section: explosion protection measures

Principles of explosion protection

§ 10. (1) If the formation of explosive atmospheres cannot be ruled out, employers shall have to take the technical or organisational measures to protect against explosions in the following order of precedence:

1.

The formation of explosive atmospheres or at least of potentially explosive atmospheres is to be prevented (primary explosion protection).

2.

If this is not possible due to the nature of the operations, effective ignition sources in potentially explosive atmospheres are to be avoided (secondary explosion protection).

3.

If this is not possible in organisational and technical terms, measures shall be taken to limit the harmful effects of a possible explosion in such a way as to ensure the health and safety of workers (constructive explosion protection).

(2) In order to protect health and ensure the safety of workers, employers must, in accordance with the principles laid down in paragraph 1 above, and on the basis of the identification and assessment of the risks of explosions, require the necessary take technical and organisational measures to ensure that explosive atmospheres are designed so that the work can be carried out safely.

(3) The measures referred to in paragraph 1 shall be subject to regular review if necessary, but in any case if there are substantial changes.

Primary explosion protection:
Preventing the development of potentially explosive atmospheres

§ 11. (1) Employers shall ensure that the preparation, design and implementation of operations is carried out in such a way as to avoid the occurrence of potentially explosive atmospheres and, in particular, to ensure that the following measures are taken in accordance with the following: Paragraphs are to be taken.

(2) Insofar as fire-hazardous materials (Article 40 (2) of the ASchG) cannot be replaced, their quantity in the workplace must be limited to the extent strictly necessary for the progress of the work, but not at most to the daily requirements. Spilled fire-hazardous agents must be removed without delay, taking into account the necessary precautions. Waste and residues must be removed safely and disposed of.

(3) The release of combustible gases, vapours, mists, dusts or explosive atmospheres in operations or from operating facilities shall, if possible, be avoided by the use of

1.

closed operating facilities or

2.

Systems with such low leaks that no explosive atmospheres can arise.

(4) If the measures referred to in paragraph 3 do not prevent the formation of potentially explosive atmospheres, the releases shall be:

1.

to record in full at their point of departure or formation, where this is possible according to the state of the art, and then to take place without danger to the workers, or

2.

to take appropriate natural or mechanical ventilation measures.

(5) It is necessary to ensure that gases or vapours of fire-hazardous materials, which are lighter or heavier than air, cannot accumulate in higher or lower areas, where they may form potentially explosive atmospheres.

(6) dust deposits must be avoided as far as possible. For the elimination of deposits of fire-hazardous dusts, processes such as wet cleaning processes or sucking methods in which whirling is avoided as far as possible are used. Cleaning equipment, such as industrial vacuum cleaners or sweeping machines, must be suitable for the suction of combustible dusts or combustible liquids. If light metal dusts are deposited in wet cleaners, the possible development of hydrogen as a hazard should be taken into account in the determination and assessment.

(7) There is no classification in zones and the formation of potentially explosive atmospheres in normal operation cannot be ruled out. In any case, continuously measuring devices must be used. At the latest when the warning and alarm conditions are reached, the workers are at most 50% of the lower explosion limit (UEG), acoustically and, if this is not sufficient, also to warn optically. The triggering of the warning and alarm can also be carried out on the basis of other criteria which ensure comparable safety, for example by monitoring of inerting, suction or mechanical ventilation systems.

(8) Where continuously measuring devices are used in combination with automatically initiating measures to reduce the concentration, e.g. the introduction of suction or mechanical ventilation systems or the introduction of shutoff processes, such as shall be switched on so early that 50% of UEG cannot be exceeded.

(9) Where this Regulation or the state of the art requires a higher level of security, lower than the values set out in paragraphs 7 and 8 shall apply.

§ 12. (1) Explosive areas shall be classified in zones by the extent, frequency and duration of the occurrence of explosive atmospheres as follows:

1.

Zones for flammable gases, vapours, fog:

a.

Zone 0: Range in which explosive atmospheres are present as a mixture of air and combustible gases, vapours or mists, over long periods of time or frequently.

b.

Zone 1: Area in which, in normal operation, explosive atmospheres may occasionally form as a mixture of air and combustible gases, vapours or mists.

c.

Zone 2: Area in which explosive atmospheres as a mixture of air and combustible gases, vapours or mists do not normally occur, or occur only for a short time, in normal operation.

2.

Zones for combustible dusts:

a.

Zone 20: Area in which explosive atmospheres in the form of a cloud of combustible dust contained in the air are present continuously, over long periods of time or frequently.

b.

Zone 21: Area in which, in normal operation, explosive atmospheres may occasionally form in the form of a cloud of combustible dust contained in the air.

c.

Zone 22: Area in which explosive atmospheres in the form of a cloud of combustible dust contained in the air normally do not occur, or occur only for a short time, in the form of a cloud of combustible dust contained in the air.

3.

Zones in medically used spaces:

a.

Zone G: Also referred to as "enclosed medical gas systems", comprises-not necessarily all-enclosed-cavities in which permanently or temporarily explosive mixtures are produced, guided or used in small amounts.

b.

Zone M: Also referred to as "medical environment", comprises the part of a room in which explosive atmospheres are used by the use of analgesics or medical skin cleansing or disinfectants, but only in small quantities and only for a short time.

(2) If a potentially explosive area or zone exists only temporarily for the duration of certain work (such as maintenance, cleaning, testing and disturbance), a temporary classification or classification shall be provided for that period; or Promotion to take place.

(3) Where measures are temporarily set in a given zone to ensure that there is no explosion hazard zone or zone for the duration of certain work, a temporary temporary Promotion or promotion.

(4) Explosive areas accessible to workers shall be marked, at least with the warning sign "Warning of explosive atmospheres" and the prohibition sign "Fire, open light and smoking prohibited" if: Risks to the safety and health of workers shall not be avoided or sufficiently limited by other technical or organisational measures.

2.

Floor coverings can be at least difficult to fire,

3.

Doors and gates are made of non-combustible material, can be self-closing and can be opened in the direction of escape, if there are no anti-explosion protection measures (e.g. pressure-proof design).

(2) However, if adequate safety distances of potentially explosive atmospheres are to be found to potential sources of ignition (such as furnaces or sparks) or to fire loads, only those components must comply with the requirements laid down in paragraph 1 above, which shall: have been affected by the potentially explosive area, at least:

1.

(5) Between rooms from which explosive atmospheres can escape in the danger of danger, and protected areas of escape (§ 21 Coreper), there must be sufficient ventilation locks to prevent the escape of the air from the safe escape area. explosive atmospheres may occur.

Secondary explosion protection: avoidance of ignition sources

§ 14. (1) No effective ignition sources may be present in potentially explosive atmospheres. Potential sources of ignition should be avoided or limited to the extent strictly necessary. Only the work equipment strictly necessary for the operation must be used. Electrical installations must, as far as possible, be arranged outside of explosive atmospheres.

c.

static electricity, cathodic corrosion protection,

d.

electrical balancing currents,

e.

Ultrasound, non-ionizing and ionizing radiation,

Where operations can produce sparks or cause electrostatic charging and discharge, which may constitute effective sources of ignition, precautions must be taken to ensure that:

a.

prevent the emergence of such sparks, or

b.

prevent the occurrence of such charges or deduce the charges in the context of the operational possibilities without danger, such as grounding or increasing the humidity.

4.

Where operations (e.g. maintenance, cleaning, testing or troubleshooting) cannot be ruled out, effective sources of ignition (such as glow nests) must remain in a potentially explosive area after they have been carried out Measures are taken to prevent this (e.g. cleaning by qualified personnel).

5.

Clothing or personal protective equipment, in which an electric, electrostatic or mechanically induced arc or spark can be produced, which could ignite explosive atmospheres, must not be worn.
