Practical Tips and Best Practices for Choosing & Using Lead Sheeting

Choosing Lead Sheeting

Consult an Expert: For radiation protection or complex builds, always consult a radiation physicist or project engineer for thickness and configuration requirements.
Order Oversized Pieces: If in doubt, order slightly larger sheets to accommodate fitting errors, trimming, or later modifications.
Check Tolerances: Tolerances around ±0.005” (thickness) and ±0.125” (cutting) are standard. Verify if tight tolerances are needed for your application.

Handling and Safety

Proper PPE: Always wear gloves and avoid inhaling dust during cutting or installation.
Ventilate Work Area: Ensure adequate ventilation if cutting or working in enclosed spaces.
Safe Storage: Store lead sheeting on pallets and away from high-traffic areas to prevent injury.

Cutting and Installation

Use the Right Tools: Lead is soft and can be cut with utility knives for thin sheets, or power tools for thicker plates.
Seal Joints: For waterproofing, use appropriate adhesives and sealants compatible with lead.
Minimize Seams: Fewer joints reduce the possibility of leaks or radiation “hot spots”.
Clean Surfaces Before Installation: Remove dust, debris, or oxidation to ensure a secure fit and seal.

Environmental and Disposal Advice

Never Burn or Incinerate Lead: Always recycle unused pieces through certified lead recyclers.
Follow Local Regulations: Discard packaging and unused materials according to environmental guidelines.
