Some activities, though essential in our day-to- day lives, are greatly harmful if extra care is not taken while carrying them out. Shrink wrapping ensures the public is kept safe and free from potential hazards when such activities are carried out. This is called containment and requires a great deal of skill and expertise because of the sensitivity involved. Such activities include asbestos removal, grit blasting, demolitions and paintings.
Asbestos removal is a highly sensitive activity because inhaling of the gases produced during the removal processes hazardous and may even be cancerous. The shrink wrapping is air-locked, thus, preventing any of the emissions from diffusing into the air. Demolitions mainly involve the use of explosives, especially for large projects. Hence, the shrink wrapping prevents any debris from reaching the public vicinity. The process of painting involves the use of chemicals which may be irritating. Thus, spillage is prevented using shrink wrapping.
Application of containment
The shrink wrapping used can be specified according to the activity being carried out for a short period. Containment is applied in different sectors of the economy such as in packaging factories, chemical plants, nuclear power stations and even in hospitals. This method is highly recommended for any activity which is prone to hurt the surrounding environment. Containments help in reducing worker exposure to the general public, adjacent building occupants.
Exposure often leads to tampering with the public due to curiosity. Also, there is less distraction from the surrounding environment. Hence, productivity is higher, and projects will be completed right on schedule.
Containment as a preventive measure
Containment is also used in construction sites where a period is needed to allow hardening of materials such as concrete and drywall mud. If tampered with, it may lead to delays in the schedule or even rescheduling of the entire project which may be quite time-consuming and reduce cost-effectiveness. Also, containment is used to prevent unauthorised access by the public. This will decrease cases of injuries caused by these activities and will also reduce tampering with the projects.
Benefits of containment
Containments are cost-effective as they prevent any damage to the general public which usually leads to massive losses which may derail a project. Also, shrink wrap flame retardant, thus, in case a fire occurs while carrying out any of the mentioned activities, it won’t spread to the surrounding environment.
How to make a containment
This method mainly involves wrapping the shrink wrap generally on the scaffolding and then welding the wrapping into place or using strong adhesives to do the same to produce the “skirt effect”. The use of adhesives is, however, unadvisable because it leaves behind a residue which may be hard to remove. Creating a final seal between the shrink wrap sheeting by using a wooden batten to fix the sheeting to the lowest lift of the scaffolding. Weighing down the final seal can be used in place of the wooden batten.
