Oxidizers should be stored in a cool and dry location. Segregate oxidizers from all other chemicals in the laboratory. Minimize the quantities of strong oxidizers stored in the laboratory. DO NOT return excess chemicals to the original container. Impurities may be introduced into the container which may cause a fire, explosion or other unwanted event or contamination.
Anticipate emergency situations, have proper handling equipment in the lab and readily available for spills. Check the MSDS to determine what is appropriate. Spill control materials for oxidizers are designed to be inert and will not react with the reagent i. In the event of a spill or adverse reaction notify lab personnel immediately that an incident has occurred.
Turn off all ignition sources if this can be done safely; vacate the area and call for assistance. Laboratory emergencies should be reported to the public safety office at Public safety will also contact the Office of Environmental Health and Safety at Communicate the following:.
All materials contaminated with oxidizing chemicals pose a fire hazard and should be disposed of as hazardous waste. If you do not have a waste container, contact the hazardous waste hotline at and leave a message, including your name, location and question. The inner receptacles must be packed in suitable outer packagings to a maximum gross weight of 30kg. Alternatively the receptacles may be packed in shrink-wrapped or stretch-wrapped trays with a maximum gross mass of 20kg.
Oxidising and organic peroxide chemicals not in EQ or limited LQ must be packaged in UN performance packages but must additionally meet the general or special provisions laid down.
The permitted type s are specified for each type of organic peroxide. Other packages must be marked with the UN number and show the appropriate danger sign s as specified for the good in the Dangerous Goods List. The danger sign s must be at least mm x mm where possible, and on IBCs and large packages the UN number and the danger sign s must be shown on two opposing sides.
Packages or receptacles, other than EQ and LQ packages, have to show the UN number not required to be in a framed diamond and also the appropriate danger sign s as specified in ADR. BS provides a standard for assessing the capability of pressure-sensitive label substrates and printing on them against this requirement. The consignor must provide a dangerous goods document, which in the UK is normally expected to be the in the form of a dangerous goods note along the lines of the example shown in the IMDG Code , giving the following information, in this order.
The PSN including any chemical names required in brackets or the special limited quantity description. The dangerous good note may be transmitted electronically, in which case the signature should be replaced by the name of the person, shown in capitals.
Where the goods are offered for carriage by sea in a freight container or on a vehicle which is to be carried, then the person responsible for the loading and securing of that transport must provide a certificate of compliance with the requirements.
Provision exists for this on the standard dangerous good note in addition to the dangerous goods details but should be completed and signed only by the person having such responsibility. The person with control of the final loading of a transport unit a freight container or Ro-Ro vehicle must ensure that the goods are securely packed and adequately braced, and where dangerous goods are part of the load these should preferably be readily accessible.
Before loading, the person must ensure that the transport unit is clean, dry and fit to receive the goods and that they have the dangerous goods declaration for each of the goods.
They must ensure that the goods are externally examined to ensure that they are free from damage or leakage and are properly labelled. Incompatible goods details of which are complicated and for which reference to the IMDG Code is required should not be packed in the same transport unit. Drums must be loaded in an upright position unless authorised by the relevant competent authority. The person who has been responsible for the packing of the transport unit must provide a container or vehicle certificate certifying that the above and the placarding have been carried out as required.
Before loading a transport unit all marks that are no longer relevant should be removed or covered.
Transport units should show placards mm x mm corresponding to the labels on the dangerous goods inside, including the marine pollutant mark if applicable. Where the transport unit contains goods of a single UN number this number should be shown in the bottom of the placard.
In addition to the placards, tank transport units must also show the PSN on both sides of the unit and the UN number, which must be on a separate rectangular orange plate close to the placards or in the lower half of the placard. Where the transport unit contains goods in LQ packages, no danger sign placard is required but the unit should be clearly marked with an enlarged version of the LQ mark, inclusive of those being distributed containing personal care or household products.
Also, if applicable, the enlarged version of the marine pollutant mark side length of mm should be shown. Operational provisions of the ship, which are outside the scope of these volumes, may also affect the shipment. For example, rules on the stowage of goods on board ships may preclude the shipment of the goods on a particular sailing.
After the transport unit has been unloaded, precautions should be taken to ensure that there is no contamination left that can be a danger. Danger placards and other marks that are no longer relevant should be removed. They state the general conditions that have to be complied with before the goods can be transported by air, including permission for the operator to carry dangerous goods.
This means they effectively apply to civil flights globally. Organic peroxide goods, apart from a number of technically pure substances listed in Appendix C of the International Air Transport Association IATA Dangerous Goods Regulations, must have the approval of the appropriate authority of the state of manufacture before shipment. This approval must include any additional relevant transport conditions and must include the test results on which classification was based.
This approval needs to be at least in English as it is required to accompany the documentation. Oxidising goods are prohibited from being carried on board the plane in checked or carry-on baggage or on the person.
The only exceptions are small oxygen generators UN intended for use by the person carrying them. These are permitted only if they are carried in checked baggage. Organic peroxides requiring temperature control are prohibited on planes unless specially exempted , as are those requiring a supplementary explosives danger sign. Oxidising goods are not permitted to be carried by airmail. Certain airlines may have more restrictive variations that prohibit the carriage of oxidising goods.
Since the air mode, along with the other modes, has adopted the UN provisions for EQs. Specific requirements apply to the receptacles, closures and fill levels, to use of cushioning, and to the tests that the package must be capable of withstanding.
Other than excepted packages covered by the above, packages must meet all the general packaging requirements of ICAO. Some oxidising agents of Division 5. Such goods must be packaged in relatively small inner receptacles, according to the limits given in the list of dangerous goods.
The packages must be capable of meeting defined tests a 1. However, they do not need to be independently certified and carry special package type markings.
Passenger packages are receptacles or packages ie inners with outers which meet the restrictions of ICAO for the maximum amount permitted per receptacle and per package for carriage by passenger carrying planes. The packages must meet the general conditions of packaging and the provisions of the applicable PI.
The requirement to meet the general conditions means that any receptacles used for liquids must be capable of meeting a special hydraulic pressure resistance. Packages containing receptacles must have been tested and certified by a body recognised by the competent authority as meeting the requirements of the UN Recommendations on the Transport of Dangerous Goods — Model Regulations, as reproduced in ICAO. Design type specification covers many aspects which must be complied with for the packages as shipped — the receptacle used and the materials and method of closure of the outer packaging must all conform to the design type tested.
Such packages are acceptable on passenger carrying and cargo-only flights. Cargo packages are packages as above but where the maximum quantities permitted per receptacle and in the package are greater. Single packagings receptacles may also be permitted to the sizes specified in the PI for the goods. Limited quantity, passenger and cargo packages must be labelled with the appropriate Division primary hazard diamond label and with any required subsidiary hazard diamond.
Additionally, the packages must be marked with the name and address of the consignee and consignor. Limited quantity packages must be additionally be marked with special air variant of the LQ mark. It is hoped that the surface modes will also thus recognise such air LQ packages as meeting their surface requirements, despite the presence of the class danger labelling.
Also, any package restricted to cargo aircraft only must additionally bear the appropriate special label. All markings must be durable, clear and readily visible.
Any irrelevant markings are to be removed or obscured. Air mode regulations do not require the Environmentally Hazardous Substances EHS or Marine Pollutant MP mark on packages of oxidising and organic peroxide substances even when they meet the criteria. However, application of this mark is not prohibited. Apart from when dangerous oxidising and organic goods are packaged in accordance with the excepted package provisions, the person who offers the such goods for carriage by air must provide the operator with two copies of a dangerous goods document.
This must give the following, in English, in the order specified below. The Division 5. A statement indicating that the shipment is within the limitations for passenger or cargo aircraft, as the case may be.
For organic peroxides which are subject to having their classification approved by the state where the goods were manufactured, a copy of that approval at least in English. Special handling information for certain organic peroxides indicating that the goods must be shaded from direct sunlight and stored away from all sources of heat in well-ventilated areas and not over-stowed with any other cargo.
Where the organic peroxide is a sample authorised for transport by the competent authority, a statement to that effect. However, IATA believes that in reformatting them it has utilised its experience of writing requirements for controlling the transport of dangerous goods which were effective before the ICAO TIs were first introduced.
In addition however, IATA has introduced a few additional requirements which it believes are necessary from operational needs. Because the IATA DGRs have the full support of virtually all airlines, in practice they have the effect of global regulations covering the carriage of dangerous goods by aircraft. They demand the use of a specific form in one of two slightly different variants for the data, with red diagonal hatching at both sides. IATA requires that the Special statements eg for approved organic samples be in the additional handling box.
Also IATA will not permit any changes or alterations unless these are signed by the same person who signs the declaration. Only the Air Waybill Number, airport of departure and airport of destination may be inserted by the accepting airline; all other details must be entered by the shipper.
Details of non-dangerous goods packed with the dangerous goods are allowed, but other non-relevant information is not permitted. The form may be completed manually or by mechanical methods typewriter or computer printer. Typewritten or computer signatures are not permitted, but these may be by carbon copy or by stamp. The IATA DGRs include acceptance checklists one for radioactive materials and the second for other dangerous goods that are used by the airlines to check incoming shipments for compliance.
It is strongly recommended that the relevant form be completed by the shipper as far as is applicable before offering the shipment. This will help minimise refusals and consequent delays. In the case that the operator refuses a shipment the operator should provide a copy of the completed checklist to the shipper.
Oxidising wastes to one person may be raw materials for another. However, activities concerning dangerous waste may invoke additional requirements over and above the general requirements for all wastes and the special requirements for dangerous corrosives which have been developed to ensure that such wastes are properly dealt with, and ultimately disposed of. They set up a system of waste management licensing to ensure that wastes are properly handled and disposed of.
Basically the regulations require that, with certain exemptions, those involved in the accumulation, storage, transport or brokerage of waste do so only if they have a license, and conform to the provisions of that licence. The exemptions include the storage of returned goods that are waste pending disposal, for one month, by their supplier provided they are to be reused or submitted to a recovery operation, or they are being stored at the place where the intention to dispose of them was taken.
The HWR apply in England to wastes that have hazardous properties that need to be controlled, ie are dangerous. The Environment Agency Technical Guidance 3 provides detailed guidance on the classification of hazardous dangerous waste. The wastes must be assigned to one, or in some cases more than one, appropriate six-digit code in the list of wastes contained in the List of Wastes England Regulations LoWR as amended. This list contains absolute entries where wastes that fit the description are defined as hazardous.
In other cases there may be mirror entries, where one of the pair of entries is for hazardous wastes, having dangerous properties through classification, and the other for non-hazardous wastes, which are not dangerous according to the criteria.
An example of such a code is 20 01 27 which relates 20 01 to municipal waste that has been collected as a separate fraction which is paint, ink, adhesives and resins containing dangerous substances at such levels that the wastes are hazardous dangerous according to the criteria eg tubes or organic peroxides from two part kits. Those not hazardous dangerous being assigned to the 20 01 28 mirror entry. Hazardous wastes are not mixed with other wastes, unless permitted as part of the recovery or disposal operation, and that different hazardous wastes are separated where technically feasible.
Premises notification, with certain exceptions, is made to the Environment Agency EA prior to removal of the waste, with annual renewal thereof. A fee is payable for this. A hazardous waste consignment document Schedules 4 to 7 be generated by the producer, with subsequent completion by the consignor, waste holder, carrier, and consignee. Additional rules apply for cross border shipments within the UK eg between England and Scotland.
Producers, holders, consignors, carriers, and consignees must keep records for at least 3 years 12 months in the case of carriers. Consignees are to provide the EA and the producer or holders with a quarterly returns of hazardous wastes received. The following information is of a basic nature only; it should be used to prompt specific emergency planning, and only to provide information in the absence of those specific details. The following basic criteria can be applied to oxidising goods in circumstances where specific information is not available.
Immediately eliminate all sources of ignition and instruct others to stay well away. Open windows and close doors on way out. Consider building evacuation. Immediately drench the skin area or eyes with copious amounts of cold water for at least 10 minutes. Remove contaminated clothing. Organic peroxides are particularly damaging to the eyes and the wash out should be immediate from an eye wash bottle or by holding the eye open and washing from the inner eye outwards. Care should be taken not to contaminate the other eye with the water from the washing of the affected eye.
Do not apply oils or ointments. Cover only with a dry dressing. Seek advice from a physician at once. Remove the casualty to fresh air as soon as possible. Ensure casualty is breathing. If the casualty is unconscious, turn the casualty into recovery position. Do not leave casualty. Seek medical advice as soon as possible. Give oxygen if available in short applications, not continuous therapy. This is not normally applicable to oxidising goods. If it does occur, give the casualty plenty of water to drink.
Do not induce vomiting. Seek detailed advice from a physician as soon as possible. Where organic peroxides are involved there is danger of explosion.
The alarm should be given and the emergency services informed of the type and amount of the organic peroxides, and any other dangerous chemicals, present. The area should be evacuated and further entry prevented by hazard signs or tapes and use of staff to ensure that only emergency services are admitted to the area.
Where possible ensure that those evacuated are moved upwind of the incident and away from the path of the gas cloud. Division 5. Carbon dioxide or other inert gas will be ineffective. Unaffected packages should be moved, if this can be done safely. Where this is not possible they should be deluged with copious amounts of water to keep them cool.
Fight the fire with large quantities of water from as far away as possible and from behind cover if available. Instruct others to stay at safe distance, well away from spillage area. Stop any further leakage if possible without risk. If possible prevent liquids if any from entering sewers, basements or workpits.
Ensure that organic peroxides are kept away from rags and other combustible materials, and that eye protection is always worn. Our team are also available for on-site assessments across New Zealand, click here to request a site visit.
