## Tips for Managing Class Code 1624 Workers' Comp Costs

- Silica dust control is the top health priority — wet cutting methods and respiratory protection are required
- OSHA's silica standard (29 CFR 1910.1053) requires medical surveillance for exposed workers
- Separate installation crews under code 1747 if they work on job sites

## Safety Recommendations for Class Code 1624

- Implement a comprehensive dust control program, including wet cutting methods, local exhaust ventilation, and mandatory respiratory protection (e.g., N95 or P100 respirators).
- Ensure all saws and grinders have proper guarding and employees are trained in their safe operation, including lockout/tagout procedures.
- Provide mechanical lifting aids (e.g., slab lifters, forklifts) and training on proper lifting techniques for heavy stone.
