Introduction

The Washington Suburban Sanitary Commission (WSSC) regulates the use and operation of the sewerage system for the University of Maryland campus. The discharge of organic chemicals the sanitary sewer is stringently regulated since such materials can cause fires and explosions in the system, interfere with operations at the treatment facility, and/or pass through the treatment facility.

Introduction

Lasers and laser systems are in use everyday by individuals in virtually all fields of occupation. Industry makes use of lasers in all kinds of consumer products, which utilized for their appropriate purpose do not pose a hazard to the public. Lasers however do present a very real danger in the research community when not used properly or when individuals do not use appropriate protective equipment to prevent injury from the laser light.

Introduction

Radioactive materials are used in University laboratories because they can be traced through the radiation they emit, making them powerful research tools in biological and physical research. Radiation producing equipment such as x-ray machines, accelerators, and sealed sources can produce physical injury at high enough levels and if ingested or inhaled. Methods of protection are well understood. Strict exposure limits apply and as a result of controls which are in effect, the risk of work involving exposure to these sources of radiation is insignificant.

Introduction

Material handling can be a major source of occupational injuries whether the work is done manually or with mechanical assistance. Jobs that involve manual, mechanical, or repetitive handling present the highest risk of injury.

Introduction

Preventing back injuries is a major workplace safety challenge. According to the Bureau of Labor Statistics (BLS), more than one million workers suffer back injuries each year, and back injuries account for one of every five workplace injuries or illnesses. Further, one-fourth of all compensation indemnity claims involve back injuries, costing industry billions of dollars on top of the pain and suffering borne by employees.

Introduction

Sanitary wastewater discharges regulated by the Washington Suburban Sanitary Commission (WSSC) and the Maryland Department of the Environment (MDE) establish specific conditions under which wastewater can be discharged. This fact sheet summarizes general regulatory requirements for wastewater discharge and identifies compliance management practices for facility personnel.

Introduction

Crushed hands and arms, severed fingers, blindness, etc. are part of a list of possible machinery-related injuries. A good rule to remember is that any machine part, function, or process which may cause injury must be safeguarded. When the operation of a machine or accidental contact with it can injure the operator or others in the vicinity, the hazards must be either controlled or eliminated.

Applicable Regulations

OSHA Regulations:

Introduction

Ozone depleting substances used in refrigeration and air conditioning appliances include chlorofluorocarbons and hydrochlorofluorocarbons, collectively referred to in this fact sheet as CFCs. This group of chemicals has been demonstrated to be harmful to the stratospheric ozone layer and is subject to a production phaseout. As a result of the Clean Air Act, the EPA has established a national recycling program for these substances when recovered during the servicing and disposal of refrigeration and air conditioning equipment.

The information in the Safety Data Sheet (SDS) is usually organized into distinct sections which may include:

Introduction

The Maryland Department of the Environment (MDE) has established regulations governing emissions of pollutants into the ambient air. The State's program is based upon its compliance with the Federal Clean Air Act (CAA) which establishes the US Environmental Protection Agency's authority to set national air quality standards. In Maryland, parts of the State, such as Prince George's County, are not in compliance with the national standards and are therefore known as "non-attainment areas" subject to more stringent regulation and permitting.
