School Smart: Finding Creative Cleaning Solutions

Hi. I’m Rosemary and I’m in charge of cleaning services for a large university. It really is a challenge. From graffiti on walls to chemical spills in science labs, I ensure that anything unsightly is cleaned up quickly and safely. In the course of my job, I’ve learnt that choosing the correct cleaning service for a task is the key to efficiency. I employ a general services company to do everyday cleaning, however, we regularly hire specialist carpet cleaners and definitely use qualified services for problems like chemical spills. Lots of my family members and friends call me when they have particular cleaning problems in their businesses. I figure that the knowledge I’ve collected over the years could be helpful, so I’ve started this blog. Do let me know if it’s useful and may your surfaces always be bright!

How To Build A Mini Enclosure For Asbestos Removal

by Phillip Clark

In some older residential properties, asbestos may be found in many places. These places include as part of the water tank, as part of any textured ceiling, and outside the property—such as part of the building's roof, or as part of a felt roofing. In many cases, this asbestos can be dealt with by the owner; no special training or inspection by the local authority is required in order to remove it. However, any homeowner who is intending to remove asbestos themselves should take the time beforehand to understand how to properly deal with this dangerous material. In some cases, building a mini enclosure around the item to prevent the escape of asbestos as you work on it is a great idea. Let's look at how to do this.

Materials

The aim is to fully enclose an area, such as the water tank, to ensure that as you dismantle the asbestos filled material, none can escape into the surrounding environment. To build a mini enclosure you will need the following materials:

  • Timber for the frame
  • Thick polythene sheeting, to act as the walls
  • Duct tape
  • Smoke tubes
  • A garden hose or spray
  • Rags for wetting asbestos areas
  • A vacuum cleaner with a safe enough rating to deal with the vacuuming of the asbestos
  • Suitable bags or sacks to secure the material once removed.

The Frame

The frame should be big enough to allow the person to work comfortably inside of the enclosure. Use the timber to erect the frame, and attach the polythene sheeting to make the walls. Use the duct tape to secure the polythene to the timber. Remember to include an access to the mini enclosure. To do this, make a slit in one of the walls. Fix a length of polythene from the inside of the enclosure so that this slit is covered. Once you have the enclosure built, you must test it to ensure that it is sealed properly.

Smoke Test

Two people are required for this test. One stands inside the enclosure, and releases smoke around the seals of the frame. The other person should inspect to see if there are any leaks allowing the smoke to escape. If this is the case, re-seal, and re-test. Once done, remember to place all of the other materials (the rags vacuum cleaner and sprayer) inside the tent.

Always work carefully inside the enclosure. When dismantling, reverse the steps and place all materials into double wrapped plastic bags, remembering to label them properly.

Remember to call a professional asbestos removal company (such as Jac Asbestos Removal Pty Ltd) if you feel this is beyond your skill.
