| Who can I contact for disposal of asbestos waste? |
Singapore banned the use of asbestos in building materials in the late 1980s. If the building you are concerned with is built after 1st Jan 1991, it is unlikely to contain asbestos. Buildings that were built before 1 Jan 1991 may still contain asbestos-containing materials. If these materials are in good condition and undisturbed, the risk of asbestos fibres being released is low and would not pose significant health risks to people. They should be left alone, and removal of such materials is not necessary. For more information related to asbestos management in buildings, you may contact the following: Asbestos survey services and removal works - MOM Occupational Safety and Health Division at 64385122 or visit MOM's website. |
| How to safely dispose of used/empty cylinders containing flammable materials? |
For disposal of bulky and/or industry-use flammable materials, companies should contact the supplier of the cylinders to arrange for the collection of the used/empty cylinders. Alternatively, companies may contact licensed toxic waste collectors to assist with the disposal. For further information related to the safe handling and disposal of industry-use flammable materials, companies may refer to the guidelines. For household generated waste such as an empty propane canister, members of the public are advised to fully consume the flammable products first before placing them in the blue recycling bins. For the disposal of used liquefied petroleum gas (LPG) cylinders, refer to the advisory on the use of LPG here. For more information, contact the NEA hotline at 1800 6225 5632 or submit your feedback electronically via the Online Feedback Form available on the NEA website, the myENV or OneService mobile application. |
