Proper Setup And Execution For Dry Ice Blasting Historical Structures

Dry ice blasting any historical structure is a huge responsibility for a cleaning contractor. The owners are counting on your expertise and professionalism to...

A) Salvage their historic structure without the cost and time delays of replacing the classic, original materials with new, more modern, but less artistic building materials and...

B) Protect the job-site from flying debris, secondary waste and potentially hazardous, airborne dust, debris, toxins and hazardous wastes.

As a professional dry ice blasting contractor on a historical restoration project, your safety and compliance responsibilities include (but are not limited to) the following:

    Protect your Employees with the appropriate Personal Protection Equipment (PE's). Be sure that all employees have been trained in proper PPE use and are aware of what contaminants they might be expected to encounter on the job. Hold daily 'Toolbox Talks' to reinforce good behaviors and curtail bad practices before they become dangerous habits.

    Protect all other Trades and contractors by containing and isolating your work area. Construct appropriate work partitions and control pedestrian traffic, directing trades away from or around your work zone. Never allow other trades inside your work area unless absolutely necessary. Insist on detailed orientation sessions for any trade scheduled to work within your work zone and always include these trades in your daily Toolbox Talks and safety meetings for as long as they are working alongside you and your crew.

    Minimize Dust, flying debris and airborne particulate. Tight ambient controls are mandatory. Use filters, back-stops and seal all possible exfiltration potentialities. You are responsible for any and all debris you create and it will always be on your best interest to contain and control all the dust your create before it infiltrates other work areas and damages other structures.

    Air Quality! You are responsible to capture and treat all ambient air and control all air-flow in your work area. Dry ice blasting creates no breathing or safety hazards on its own, but the contaminants you are cleaning will likely become airborne. The air you contaminate is always your responsibility. Control every aspect of your work zone for maximum safety.

    Contain & Collect all hazardous materials such as lead-based paints, asbestos, heavy metal coatings, mold, mildew, char and misc contaminants. Wherever hazardous materials are present, tighten up your control methods to ensure job-site safety at all costs.

Of course, as important as containment and segregation is to ensuring the safety of your employees and the other trades on the building restoration site, it is also imperative that all modes of safe egress are maintained at all times.

Post exit strategies and alternate egress pathways at any place where your work zone interferes with the normal traffic routes, pathways and exits.
