Dry Ice Blasting Historical Structures: Proper Setup And Execution

Cleaning any ancient structure with dry ice blasting is a major duty for a cleaning company. The business owners rely on your knowledge and skills to…

A) Preserve their historic structure without incurring the costs and time delays associated with replacing classic, original elements with new, more contemporary, but less aesthetic building materials, and…

B) Prevent flying debris, secondary waste, and possibly harmful airborne dust, debris, poisons, and hazardous wastes from entering the jobsite.

Your safety and compliance duties as a professional dry ice blasting contractor on a historical restoration project include (but are not limited to) the following:

Personal Protective Equipment (PE) is a great way to keep your employees safe. Ascertain that all personnel have received adequate PPE training and are aware of the toxins they may face on the job. Hold daily ‘Toolbox Talks’ to reinforce positive actions and prevent poor habits from developing into harmful routines.

By confining and isolating your work space, you can protect all other trades and contractors. Construct adequate work dividers and guide pedestrian traffic away from or around your work zone. Allowing other trades into your work area should only be done if absolutely required. For as long as they are working alongside you and your team, insist on full orientation sessions for every trade scheduled to operate inside your work zone. Include these trades in your daily Toolbox Talks and safety briefings.

Minimize Dust, flying debris, and particulate matter in the air Ambient restrictions must be strict. Filters, backstops, and seals should be used to prevent any possible exfiltration. You are responsible for any and all debris you make, and it is always in your best interest to contain and manage all dust before it spreads to other work areas and causes damage to other structures.

Excellent Air Quality! You are responsible for capturing and treating all ambient air in your work area, as well as controlling all airflow. Dry ice blasting does not pose any respiratory or safety risks in and of itself, but the pollutants you’re removing will almost certainly become airborne. It is always your obligation to clean up the air you contaminate. For optimal safety, control every element of your work zone.

All hazardous items, including as lead-based paints, asbestos, heavy metal coatings, mould, mildew, char, and other pollutants, should be contained and collected. Tighten up your control systems whenever hazardous items are present to ensure job-site safety at all costs.
Of course, as critical as containment and segregation are for the safety of your workers and other trades on the building restoration site, all routes of safe egress must be maintained at all times.

Anywhere your work zone interferes with typical traffic routes, paths, or exits, provide exit plans and alternate egress pathways.
