Best Practices for Regulatory Compliance
1. Document Everything
Maintain complete records of container certifications, inspections, treatments, and chain of custody. Documentation is your primary defense in regulatory audits.
2. Know Your Product
Understand the hazard classification of your contents. This determines container requirements, labeling, and storage restrictions.
3. Inspect Regularly
Implement routine container inspection programs. Check for damage, corrosion, leaks, and label legibility before each use.
4. Train Your Team
Ensure all personnel handling containers understand applicable regulations. Required training includes HazCom, HAZWOPER, and DOT certification where applicable.
5. Work with Certified Suppliers
Source containers from reputable suppliers who can provide documentation of UN certification, FDA compliance, and other required certifications.
6. Stay Current
Regulations change frequently. Subscribe to regulatory updates from DOT, EPA, OSHA, and FDA to stay informed of changes affecting your operations.
7. When in Doubt, Ask
Regulatory compliance can be complex. When uncertain, consult with regulatory experts, your container supplier, or the relevant regulatory agency.
8. Plan for Disposal
Know the proper disposal or recycling procedures for your containers. Improper disposal can result in significant fines and environmental liability.
