To provide general safety recommendations when working in and handling various materials in a glove box. Since each glove box is unique in its application and operation, specific manufacturers’ recommendations and operating procedures should be obtained and followed to ensure safe and proper use.
There are many applications for glove box use. Including, but not limited to:
Please refer to individual manufacturers’ specifications and guidelines.
Any persons charged with the transport, storing, installation, commissioning, operating, maintenance and/or service of the glove box must be properly trained in its use. Prior to installation, initialization and operation of the system, the operations manual should be read in its entirety and be located in a suitable area near the system to allow for easy reference. Authorized individuals should be properly trained by either the manufacturers’ technical representative or a member of their department proficient in the use of the glove box. (PI or co-worker)
In addition to the guidelines and information contained within the manual, all internal, local health, safety and environmental guidelines should be followed. It is the responsibility of the user to follow all local health, safety and environmental guidelines with regards to the handling and disposing of substances that may be injurious to health. This also applies to the disposal of vacuum pump oil and all components and filtering devices that come in contact with gas flow within the unit.
The following general safety guidelines must be considered when working with inert gas concentrations:
Improper use or operation by persons not qualified may result in danger to the:
General hazards of the system may arise in the following ways:
Under normal operation conditions the box may be operated under various pressures. However in the unlikely case of a failure of a valve, the box may become exposed to extreme pressures. The standard safety feature to prevent a dangerous situation arising from this malfunction is provided by the glove itself. The fixture of the glove has been designed in a way that the glove will be dismounted before any damage is caused to the box.
When handling materials with mechanical, pneumatic or vacuum systems it is possible that materials may be ejected. Extreme caution should be taken to avoid any possible contact with the ejected materials without proper protection.
Simultaneous operation of the system by two or more persons is not recommended as this may cause hazards based on misconduct or mutual misunderstanding. In case of the system being operated by two or more persons, operation should be conducted in such a way as to ensure each individual’s respective task does not influence other tasks in any way.
Safety covers, panels, panes, windows or doors may not be removed at any time, unless there is a need for service. The system may not be opened (i.e. antechambers, etc.) during processing or power failures. In the case of any safety deficiencies, the system must be decommissioned and the service personnel informed accordingly. During decommissioning compliance with all local health, safety and environmental guidelines must be followed.
This system operates under high voltage. Risk of injury caused by high voltages exists anytime the system is connected to the power supply, this includes when the system is powered off.
Connection to the main power supply must be performed by a qualified electrician according to local area guidelines. All neutral and ground wires must be connected accordingly.
Service required while the system is in operation should only be performed by qualified personnel trained in the knowledge and prevention of all potentially dangerous and hazardous situations.
The system must be grounded at all times. Do not remove or cut off any ground wire for the system or its components. In case of insufficient grounding or damaged ground conductor ensure the system will be inoperable and secure it against unauthorized or unintentional operation.
Replacement of fuses should be of the same type and current rating.
Proper handling of chemicals, corrosives and solvents is the user's responsibility. Materials used may be flammable, explosive, toxic. Below are some guidelines to refer to when handling chemical substances:
Caution: Released chemicals may react with each other, leading to unwanted and/or unknown substances, which may cause additional risks.
Biological hazards are not addressed under this policy. Please consult the Biosafety Policies for proper use and certification of Biosafety Cabinets.
All glove boxes should be properly installed and certified initially and routinely thereafter according to individual manufacturers’ recommendations.
This procedure shall be reviewed once every two years, or as changes require.
