R.A. 6969 • “Hazardous wastes are substances that are without any safe commercial, industrial, agricultural or economic usage and are shipped, transported or brought from the country of origin for dumping or disposal into or in transit through any part of the territory of the Philippines.” • “Hazardous wastes” shall also refer to by-products, side-products, process residues, spent reaction media, contaminated plant or equipment or other substances from manufacturing operationsand as consumer discards of manufactured products which present unreasonable risk and/or injury to health and safety and to the environment.”
Objective and Importance of Classification of Hazardous Wastes in the Philippines • Environmental Management Bureau (EMB) • policy making body responsible for the hazardous waste management of the Philippines • objective of the EMB is to use environmental impact assessments in balancing economic growth with ecological protection • baseline information that will develop the standards for hazardous waste management, environmental monitoring and the regulation of hazardous waste disposal
Hospital Waste • different in types and increasing in amount • hospital waste added a risk for patients and personnel who handle it • poses a threat to human health and environment • all waste generated, discarded and not intended for further use in the hospital
Environmental Management Bureau Formulates plans, programs, and appropriate environmental quality standards for the prevention and control of pollution and the protection of the environment.
Environmental Management Bureau Implements Five Environmental Laws:

Emergency Response Team • Name and responsibility of the emergency response coordinator and team • Communication with authority
Emergency Response Team • Evacuation Procedure of employees and personnel • Protective and Emergency Response Equipment • Emergency Transport Procedure • Temporary Closure • Training program for personnel on site
Personnel Training • waste identification (types and characteristics) • potential hazards of the wastes • proper labeling and storage of hazardous • roles and responsibilities for implementing the emergency contingency plan • proper use of emergency equipment • first aid and safety procedures • laws and regulations concerning hazardous waste management
Waste Transporters • Allowed to transport the type of waste indicated in their registration. • Should receive waste from generators only if they have the Proper Manifest Formand Spill Response Plan. • Should receive hazardous waste properly labeled and packaged and deliver the waste to recognized treaters. • Avoid densely populated areas, watershedor catchmentareas, and other environmentally sensitive areas. • Shall have warning signs and markings regarding shipment of hazardous goods
Waste Transporters • If the waste cannot be delivered to the destination, the transporter must inform the waste generator • Ensure that hazardous waste of different sub-category or different waste generator should not be mixedduring the transport, transshipment, and/or storageof the waste. • In case of spills or accidents, the transporter shall immediately notify the DENRthrough the EMBRegional Office Region. The waste transporter must file within ten (10) days a detailed report describing the accident, spill, and containment or cleanup measures taken.
