E

Electrostatic  Electricity at rest.

Electrostatic Discharge (ESD)  The sudden transfer (discharge) of electricity from one object to another.  This static electricity is generally caused by friction of plastics or fabrics rubbing together.

Ethylene Oxide (EtO)  A very reactive organic chemical commonly used in sterilization processing.

F

Fab  A buzz word for the Cleanroom fabricating area where the product is being manufactured.

Fiber  A particle having a length 100 micrometers or greater, and an aspect ratio of at least 1:10.

G

Gamma Rays  Electromagnetic radiations from radioactive substances, such as Cobalt 60.  Similar to high energy x-rays.

Garments, Cleanroom  Special items of clothing designed to be worn to protect Cleanroom atmosphere from contaminants released by workers.  Special clothing apparel includes footwear or covers, and head covers.

Garments, Flame Resistant  Wearing apparel made of flame resistant materials which comply with the requirements of Federal Standard CS 191-53 and NFPA 702.  (Compliance with the referenced standards does not mean that the materials will not burn when directly exposed to an open flame.)

Gas  One of the three states of aggregation of matter, having neither independent shape or volume and tending to expand indefinitely.

Glove Inflator  Allows easy donning of gloves.  the gloves are inflated using air, allowing the user to put on and take off the gloves easily.

Glove Liner  Half-finger glove liners are worn under latex or vinyl gloves to absorb moisture away from the skin during extended periods of glove wear.

Glove Sealers  Seal Cleanroom gloves around the wrists of cleanroom garment sleeves.

Gloveboxes  An enclosure, with or without gloves, that services the nuclear, biomedical, semiconductor, chemical and other industries where confinement to or from the atmosphere is required using low differential pressure. (American Glovebox Society)

Gloves  Hand coverings having separate sections for each finger and the thumb.  Gloves often extend part way up the arm.  Gloves are available in latex, vinyl, neoprene, nitrile, nylon, polyester, polyurethane, PTFE, and other materials.  They are available in antistatic and conductive, chemical resistant, sterile, powdered and powderless styles in a variety of lengths and sizes, and may be ambidextrous or hand-specific.

 

H

HEPA (High Efficiency Particulate Air) Filter  A replaceable extended-media dry-type filter in a rigid frame having minimum particle-collection efficiency of 99.97% for 0.3 micrometer thermally-generated dioctylphthalate (DOP) (or specified alternative aerosol) particles, and a maximum clean-filter pressure drop of 2.54cm (1.0 in) water gage when tested at rated airflow capacity.
