Recommendations |
| Objective: Minimize and safely process wastes. |
| PPE |
- Operators should wear the correct PPE when processing wastes and sludge.
- Preservative PPE requirements should be followed as determined by the concentration and the state (liquid, solid, sludge) of the material and in accordance with label instructions. (Table 8).
|
| Minimization |
- Appropriately condition wood prior to treatment.
- Avoid the introduction of debris, soil, snow, ice and other foreign matter from wood and trams into the treatment vessel.
- Keep the treatment solution clean and ensure that solution concentrations and component balances are in accordance with acceptable standards (CAN/CSA O80).
- Minimize the frequency of switching from one preservative to another in a single treatment vessel:
- Avoid mixing trams.
- Thoroughly clean vessels, ancillary piping, etc., and trams prior to a switch.
- Do not exceed the stipulated limitations of process parameters (e.g. temperature).
- Thoroughly clean protective equipment after use.
- Thoroughly empty and clean preservative containers (if applicable):
- Rinse drums thoroughly (triple rinsed) with water prior to disposal in designated sanitary landfills subject to approval by the regulatory agency.
- Steam cleaning for oil based pesticides.
- Follow provincial instructions for any additional cleaning requirements and for disposal.
- Ensure proper stabilization or fixation methods prior to storage in the open environment
- Return containers to suppliers or reuse sound containers for storage of wastes or make the empty container unsuitable for further use and dispose in accordance with provincial requirements.
- If the discharge of contaminated runoff is required, specific approvals must be obtained from the appropriate provincial or municipal environmental regulatory agency.
- Reuse/ recycle all rinse waters for work solution preparation (for water-borne formulations)
|
| Collection |
- To be carried out by personnel trained in potential chemical hazards and appropriate handling methods.
- All personal hygiene and general precautions as outlined in Section 6 should be followed (Tables 6 and 8).
- Prescribed practice for vessel entry should be observed (see Tables 20 and 22).
- Any runoff, recuperated spills or liquid wastes generated at the site must be contained and reused as much as possible.
- Collect, drain (where appropriate) and place wastes and sludge into sealed drums.
|
| Storage |
- The contained area should be on a paved or concrete sealed surface.
- Appropriate signs identifying the storage area should be posted.
|
| Records / reporting |
- Label all drums to indicate contents (type of waste).
- Maintain an up-to-date inventory of containers, including their volumes and contents.
- Undertake all labelling, reporting and disposal activities in accordance with WHMISrequirements and applicable regulations (municipalities, provinces, federal).
|
| Transportation |
- All labelling, records and reporting should be in compliance with the TDGRrequirements.
- Classify waste in accordance with the TDGR.
- Follow reporting obligations in case of a spill or emergency (Section 12).
- Follow all instructions as outlined in Section 11, Table 27.
|
| Disposal |
- Always consult with the provincial regulatory agency to determine acceptable disposal
- Do not burn contaminated wastes (toxic gases may be formed).
- Do not use treated wood wastes as compost or mulch.
- Dispose of contaminated solid waste in sanitary landfills is subject to approval by the provincial regulatory agency.
- Contain and reuse contaminated firefighting water runoff as makeup for work solutions (to the greatest possible extent).
