Hazardous Materials & Medical Waste Management
Who We Are 
Hazardous Materials and Medical Waste Management (HMMWM) Services Section of Environmental Services Department is under Support Services Division. This Section is responsible for monitoring medical waste disposal activities.
Overview of HMMWM Responsibilities
HMMWM monitors and performs the following:
Regular disposing of sharps materials using sharps containers, adopting regulations related to sharps containers in compliance with policies and procedure of the Department.
Yellow bags with labels should be used to dispose infectious medical waste. The label should, at least, document the following:
This information is essential in fulfilling & monitoring the process. The bags should be properly tied and have the required thickness (150 microns). The contents of a bag should not exceed ¾ of its size (75%) and not so heavy thus easy to moved.
Sharps containers and yellow bags are used for sharps and medical waste only. Nothing is to be disposed in the sharps containers other than sharp materials. Likewise, yellow bags should be restricted to medical waste disposal only.
Chemical and pharmaceutical substances should have lists specifying their characteristics and amounts whether in kilograms or liters. The list should indicate whether a certain substance is corrosive, narcotic or toxic. It will be used then when the Contractor is ready to dispose them.
End user notifications and remarks (if any) regarding those two elements are of great importance since they help improve the performance of Hazardous Materials and Medical waste Management Section and to overcome mistakes.
The status of sharps container and yellow bags in target locations should be satisfactory and fulfilling the conditions as stated by Rules & Regulations. For example, a sharp container should not be overloaded above the line provided, should not be used for non-contaminated tissues or gauzes and should always contain sharps subjects only. The yellow bag should not be filled more than ¾ size of its size, should not contain any type of fluids and should not be used for the purpose the black bags are used to.
Proper and hermitic tying of the bags is of great importance since it keeps the bag secure from leakage. That is the only achieved by the use of nylon plastic ties.
Ensuring safe transportation of Hazardous and Medical Waste from Production Point (the ward or the section) to the Medical Waste Building, so that they arrived there in a safe way and fulfilling conditions. If there was any leakage of waste fluids inside the carts, then this is considered to be a violation, and an action should be taken.
Monitoring and liaising of the Contractor’s activities related to our section. For example; collection of medical waste bags, adhering to time and Policies & dealing properly with necessary precautions. The other issue is the monthly amount and weight of the yellow bags; they should be the same like those with the Contractor.
The status of the Biohazard Chamber should be optimum and all the necessary means should be available such as: Air Conditioner and Ventilator. Immediate cleaning process should be conducted right after collecting.
The chemical and toxic substances should be accompanied with a list specifying item name, weight and characteristics. This list should first be sent to Environmental Services Department in order to study the substances and to arrange with the Contractor to come and collect them later on.
