814.012 Ordinance of 27 February 1991 on Protection against Major Accidents (Major Accidents Ordinance, MAO)
Ordinance on Protection against Major Accidents
(Major Accidents Ordinance, MAO)
of 27 February 1991 (Status as of 1 June 2015)
on the basis of Article 10 paragraph 4 and Article 39 paragraph 1 of the Federal Act of 7 October 19831 on the Protection of the Environment (EPA) and Article 47 paragraph 1 of the Waters Protection Act of 24 January 19912,3
1 The purpose of this Ordinance is to protect the public and the environment against serious harm or damage resulting from major accidents.
2 It applies to:
establishments where the threshold quantities for substances, preparations or special wastes specified in Annex 1.1 are exceeded;
establishments where an activity involving genetically modified or pathogenic organisms or alien microorganisms subject to compulsory containment is carried out which is to be assigned to Class 3 or Class 4 in accordance with the Containment Ordinance of 9 May 20123;
railway installations in accordance with Annex 1.2a;
transit roads, as defined in the Ordinance of 6 June 19835 on Transit Roads, where dangerous goods are transported or transhipped in accordance with the Ordinance of 17 April 19856 on the Carriage of Dangerous Goods by Road (SDR) or the relevant international agreements;
the Rhine, where dangerous goods are transported or transhipped in accordance with the Ordinance of 29 April 19707 on the Carriage of Dangerous Goods on the Rhine (ADNR);
pipeline installations as defined in the Pipelines Ordinance of 2 February 20009 which meet the criteria specified in Annex 1.3.
2bis The enforcement authority may exempt establishments under paragraph 2 letter b from the scope of this Ordinance that
only carry out Class 3 activities with organisms in accordance with Annex 1.4 which, due to their properties, cannot spread uncontrollably among the public and in the environment; and
due to their hazard potential, cannot seriously harm the public or the environment.10
3 In individual cases, the enforcement authority may make the following establishments, transport routes or pipeline installations subject to this Ordinance if, on account of their hazard potential, they could cause serious harm to the public or damage to the environment:11
establishments handling substances, preparations or special wastes;
establishments where an activity involving genetically modified or pathogenic organisms or alien microorganisms subject to compulsory containment is carried out which is to be assigned to Class 2 in accordance with the Containment Ordinance, in consultation with the Swiss Expert Committee for Biosafety;
transport routes outside establishments, where dangerous goods are transported or transhipped in accordance with paragraph 2;
pipeline installations as defined in the Pipelines Ordinance of 2 February 2000 which do not meet the criteria specified in Annex 1.3.15
4 This Ordinance does not apply to installations and forms of transport which are subject to legislation on nuclear energy and radiological protection, insofar as the associated radiation could cause harm to the public or damage to the environment.16
5 The provisions of Article 10 EPA are directly applicable to establishments or transport routes which, in the case of exceptional events, could cause serious harm to the public or damage to the environment not arising from substances, preparations, special wastes or dangerous goods, or from genetically modified or pathogenic organisms or alien organisms subject to compulsory containment.17

3 The hazard potential is the sum of the effects which could arise from the quantities and properties of the substances, preparations, special wastes, organisms or dangerous goods in question. 2
4 A major accident is an exceptional event occurring in an establishment, on a transport route or in a pipeline installation which has significant effects:3
outside the operating area;
on or near the transport route;
near the pipeline installation.
5 The risk is determined by the extent of the possible harm to the public or damage to the environment resulting from major accidents and the likelihood of their occurrence.

Art. 6 Assessment of the summary report, risk report
1 The enforcement authority shall verify that the summary report is complete and correct.
2 In particular, it shall verify:
in the case of establishments, whether the estimate of the extent of possible harm or damage (Art. 5 para. 1 let. f) is plausible;
in the case of transport routes, whether the estimate of the likelihood of a major accident causing serious harm or damage (Art. 5 para. 2 let. d) is plausible.
in the case of pipeline installations, whether the estimate of the likelihood of a major accident causing serious harm or damage (Art. 5 para. 3 let. d) is plausible.
3 Following an on-site inspection, where appropriate, it shall assess the validity of the assumption that:
in the case of establishments, serious harm to the public or damage to the environment arising from major accidents is not to be expected;
in the case of transport routes, the likelihood of occurrence of a major accident causing serious harm or damage is sufficiently low;
in the case of pipeline installations, the likelihood of occurrence of a major accident causing serious harm or damage is sufficiently low.
3bis The enforcement authority shall set out the results of its assessment in writing.3
4 If the assumption in accordance with paragraph 3 is not valid, it shall order the person responsible to prepare and submit to it a risk report in accordance with Annex 4.4

Art. 7 Assessment of the risk report
1 The enforcement authority shall review the risk report and assess whether the risk is acceptable. It shall set out its assessment in writing.1
2 When evaluating the acceptability of the risk, it shall take account of local risk factors and pay particular attention to the fact that the likelihood of occurrence of a major accident must be all the lower:
the more the need to protect the public or the environment against serious harm or damage arising from major accidents outweighs private and public interests in the operation of an establishment, a transport route or a pipeline installation;
the greater the extent of the possible harm to the public or damage to the environment.
1 Amended by No I. of the O of 29 April 2015, in force since 1 June 2015 (AS 2015 1337).
Art. 8 Additional safety measures
1 If the risk is unacceptable, the enforcement authority shall order such additional measures as may be required. If necessary, these may include restrictions or prohibitions on operations and traffic.
2 In the case of measures for which a different public body is responsible, the enforcement authority shall submit appropriate requests to the competent authority. If necessary, the Federal Council shall coordinate the adoption of measures.
Art. 8a1Change in circumstances
1 If the person responsible has prepared a summary report, but not a risk report and if the circumstances change significantly thereafter or relevant new findings become available, they must amend the summary report and resubmit it to the enforcement authority.
2 If the person responsible has prepared a risk report and the circumstances change significantly thereafter or relevant new findings become available, they must:
amend the risk report and resubmit it to the enforcement authority;
amend the summary report instead of the risk report and resubmit it to the enforcement authority if:
serious harm to the public or to the environment from major accidents need no longer be expected,
in the case of transport routes and pipeline installations, the probability of a major accident causing serious harm is sufficiently low.
1 Inserted by No I of the O of 29 April 2015, in force since 1 June 2015 (AS 2015 1337).
Art. 8b1Inspections
1 In order to verify if the person responsible is fulfilling their duties under this Ordinance, the enforcement authority shall conduct regular on-site inspections. It shall set out its assessment in writing.
2 The enforcement authority shall decide on the frequency of inspection based on the hazard potential, the type and complexity of the establishment, transport route or pipeline installation and the results of earlier inspections.
Art. 9 and 101
Section 3 Response to Major Accidents
1 The person responsible shall make every effort to respond to major accidents.
2 In particular, he shall:
immediately tackle major accidents and notify the point of contact;
immediately secure the accident site and prevent further effects;
remedy any effects as soon as possible.

Scope and summary report
Annex 1.11
(art. 1 and art. 5)
Threshold quantities for substances, preparations or special wastes
2 Determination of threshold quantities
21 Substances or preparations
1 For substances or preparations listed in the table under number 3, the threshold quantities specified therein apply.
2 For other substances or preparations, the person responsible shall determine the threshold quantity using the criteria specified in number 4 in accordance with Annex I of Regulation (EC) No 1272/20082 and the criteria specified in number 5 for highly active substances and preparations. The lowest threshold quantity determined in this way is decisive.
3 The person responsible need not determine the threshold quantity for a criterion or area if he can argue convincingly that the costs of acquiring the data would be disproportionate.
22 Special wastes
The Federal Department of the Environment, Transport, Energy and Communications (DETEC) shall specify the threshold quantities for special wastes designated as such in the waste list issued in accordance with Article 2 of the Ordinance of 22 June 20053 on Movements of Waste. In doing so, it shall take account of their:
3 Substances and preparations with specified threshold quantities
TQ (kg)2
4-Aminodiphenyl and its salts 3
Ammonium nitrate fertiliser with a nitrogen content ≥ 25 %
Ammonium nitrate fertiliser with a nitrogen content ≥ 25 % and a verifiable negative detonation and smoulder test

4 Ethanol fuels with various percentages of ethanol in gasoline
4 Criteria for determining threshold quantities
TQ1 = 200 kg
TQ1 = 2000 kg
TQ1 = 20 000 kg
TQ1 = 200 000 kg
Classification/labelling2
1 TQ (kg) = Threshold quantity in kg
Chemicals Ordinance, SR 813.11
If the substance or preparation is verifiably not toxic through inhalation nor dermally, for CLP categories 1+2 (H300), a threshold quantity of 20 000 kg applies and for CLP categories 3+4 (H301/H302), a threshold quantity of 200 000 kg applies.
Corrosive substances and preparations (H314) that are also categorised and labelled as «gases under pressure» (H280/ H281) and/or as oxidising gases, liquids or solids (H270/H 271/H272) have a threshold quantity of 2000 kg, unless they have a lower threshold quantity due to other criteria.
42 Physical risks
TQ1 = 50 000 kg
H220, H221, H224, H225, H226, H242, H250, H251, H252, H260, H261, H270, H271, H272
The threshold quantity relates to the net quantity of the active explosive substance.
To determine whether a threshold quantity has been exceeded, the stored quantities of flammable aerosol dispensers in the relevant CLP categories must be added together on the basis of their net mass.
43 Environmental risks
44 Other risks
5 Highly active substances (HAS)
TQ2= 20 kg
Workplace inhalation threshold in the air3
<10 ìg/m3
Effect dose (ED50)4
c. CMR substances with major accident potential
The listed criteria apply, and the order of the criteria (letters) denotes their priority, i.e. if there is a value under criteria a, criteria b and c are no longer relevant. If a person responsible for a substance/preparation that meets one of the criteria concludes based on their self-assessment that harm to the public in the event of exposure on one occasion may be excluded or that the more serious effect of the substance/ preparation is not relevant to major accidents, the substance/ preparation is not deemed to be an HAS in terms of the Major Accidents Ordinance. In order to assess whether an effect is relevant to major accidents, the definition of «Temporary Emergency Exposure Limits (TEEL-2)» applies. The Major Accidents Ordinance does not apply to establishments that handle HAS only in the form of finished products that are intended for their own use or for supply to professional or commercial users or the general public.
TQ (kg) = Threshold quantity in kg
MAK, TLV, OEL, IOEL, etc.
Corresponds to the effect dose ED50 of 0.17 mg/kg at a body weight of 60 kg. The effect dose relates to the worst effect of the substance/preparation according to the self-assessment by the person responsible.
