The incineration chamber design provides the necessary dwell time (approximately 1 second) and high temperatures (minimum of 900°C).

(c) Quenching hot waste gases (providing utilization of heat), to reduce residence time in the critical region of temperature in the waste gas system;

(c) Modification of process design to ensure complete combustion, thus preventing the formation of persistent organic pollutants, through the control of parameters such as incineration temperature or residence time;

The modification of process techniques to optimize combustion conditions is an important and effective measure for the reduction of PCDD/F emissions (usually 850°C or higher, assessment of oxygen supply depending on the heating value and consistency of the wastes, sufficient residence time - - 850°C for ca. 2 sec - - and turbulence of the gas, avoidance of cold gas regions in the incinerator, etc.).

Retaining valves and closure mechanisms not used to define the quantity measured must, if necessary, have relief valves in order to dissipate any abnormally high pressures which may arise in the measuring system.

REQUIREMENTS FOR RESTRAINING TRAPPING METHODS

INSTALLATION OF SEAT BELTS AND RESTRAINT SYSTEMS

Confirmation of adequacy of final containment measures

Determination of final classification and containment measures

A restraining trapping method would meet the Standards if:

rinsing (only applies to retention toilet discharge equipment),

Belts or restraint systems fitted with an emergency locking retractor:

Determination of final classification and containment measures required for the activity.

Belts or restraint systems fitted with an automatically-locking retractor:

Where such loss is reasonably foreseeable, additional containment measures may be required.

Examples of chemical containment measures could be disinfectant solutions maintained in drainage systems.

pre-loading or filling with additive (only applies to retention toilet discharge equipment),

Confirm final classification and containment measures are adequate by revisiting Procedure 1.

The corresponding set of containment and other protection measures indicated in Annex IV are used as a reference set of measures to determine whether more stringent containment and control measures are required to control identified harmful effects.

In the evaluation of whether or not a restraining trapping method meets these Standards the welfare of an animal that is trapped must be assessed.

Scale will also influence which table in Annex IV has the most appropriate containment and control measures to be considered.

provision to fit holding tanks on a temporary basis in areas of use where the discharge of human waste is restricted.

Declaration by the Government of Canada concerning an accelerated phase-out period for conventional steel-jawed leghold restraining traps

The use of all jaw-type leghold restraining traps will be prohibited in Canada for the following species at the date of entry into force of the Agreement:

If there are any uncertainties in the final classification and containment conditions, it is advisable to contact the competent authority.

of which the safety belts or restraint systems have not been approved in accordance with Directive 77/541/EEC, as amended by this Directive;

'In the case of safety belts or restraint systems for front outboard seating positions, except if these are harness belts, the buckle shall also be capable of being locked in the same manner.'

prohibit the placing on the market of such safety belts and restraint systems which bear the EEC component type-approval marks prescribed in this Directive.

Once the proposed final classification and containment conditions have been determined, the level of human and environmental exposure should be reassessed (Procedure 1). This should confirm that the possibility of any harmful effects occurring, taking into account the nature and scale of the work and the proposed containment conditions are acceptably low.

- the initial classification is higher than the activity warrants and accordingly a lower classification with its attendant containment conditions would be appropriate.

A comparison of the initial classification and associated containment measures with the final class and containment requirements can give rise to three results:

- the initial classification was correct and the attendant containment measures adequately prevent or minimise harm to human health and the environment,

Where no safety belts are required any type of safety belt or restraint system conforming to this Directive may be provided at the choice of the manufacturer.

if the safety belts or restraint systems of this type of vehicle or of these vehicles have been approved in accordance with Directive 77/541/EEC, as amended by this Directive;

may prohibit the entry into service of vehicles of which the safety belts or restraint system have not been approved in accordance with Directive 77/541 /EEC, as amended by this Directive,

for restraining trapping methods, three to five years after the entry into force of the Agreement, depending on the testing priorities and availability of testing facilities;

may prohibit the placing on the market of safety belts and restraint systems, intended for installation in a vehicle, which do not bear the EEC component type-approval marks prescribed in the Directive.

in addition, in the case of safety belts or restraint system equipped with a pre-loading device comprising pyrotechnic means, the device shall have been subjected to the conditioning specified in item 2.7.10.2.'

The classification and the containment and control measures identified in the risk assessment as required to adequately contain the GMM during the proposed operations, leads to the classification of the contained use activities into classes 1 to 4. The containment and controlmeasures for each class of contained use are detailed in Annex IV of the Directive.

Based on the results of testing already available, the use of conventional steel-jawed leghold restraining traps shall be prohibited for the remaining Canadian species listed in Annex I to the Agreement, as follows:

In addition to the requirements of 3.1, Member States may, under national law, accept other types of safety belts or restraint systems covered by this Directive for certain vehicle types.

Any safety belt or restraint system approved under this Directive shall be so manufactured as to conform to the type approved by meeting the requirements set forth in 2.3, 2.4, 2.5, 2.6 and 2.7 above.

Assessment of possibility of harmful effects occurring by consideration of exposure (both human and environmental) taking into account the nature and scale of the work, with containment measures appropriate to the initial class allocated.

The standard operating procedures of individuals undertaking work with cultured GMMs such as centrifugation or sonication will have a significant impact on the effectiveness of any containment measures employed.

'Restraining trapping methods' means traps designed and set with the intention of not killing the trapped animal, but restraining its movements to such an extent that a human can make direct contact with it.

In considering the final classification and containment measures, the initial classification should be revisited to determine if it was correct bearing in mind the activities and characteristics of the operations proposed.

Notification concerning an evaluation of the installation of seat belts or restraint systems in a vehicle in accordance with item 3 to Annex I to Directive 77/541/EEC, as amended by Directives 81/576/EEC, 82/319/EEC and 90/628/EEC.

In combination with physical culture conditions that act as containment measures, both biological and chemical measures that are employed to protect the work can also contribute significantly to the containment measures that may be required.
