Glove Class
Glove class in manufacturing typically refers to the glove's ANSI/ISEA cut-resistance level, rated from A1 to A9. Higher numbers indicate greater resistance to blade cut-through. In CNC machining and millwork, glove class also denotes the type of glove approved for a specific task—such as tight-fitting nitrile gloves for coolant handling or cut-resistant gloves for deburring sharp edges.
On a CNC shop floor, glove class is a task-specific PPE selection based on hazard. For rotating machinery, gloves are strictly prohibited near running spindles, lathes, or drills due to entanglement risk. For non-rotating tasks like deburring, handling sharp sheet stock, or broken tooling, shops select higher cut-resistance ratings (ANSI A1–A9) to protect against lacerations. In wet or oily environments, slim nitrile-coated gloves improve grip and coolant resistance while minimizing snagging. Millwork operations often require abrasion/cut protection for handling knife-sharp laminate or metal trim, balancing dexterity and safety. The key decision point is matching the glove's properties to the actual hazard, not relying solely on a high cut class.
- Wearing cut-resistant gloves on rotating equipment: A glove may be cut-resistant but still mechanically unsafe around a spindle, chuck, or lathe because any fabric can be grabbed and pull the hand into the rotating part before the material fails.
- Choosing the wrong class for the task: Using a low-rated glove for deburring sharp stainless edges or raw sheet stock can tear quickly, leading to lacerations despite wearing PPE; ANSI cut class only measures blade cut-through resistance, not puncture or snagging risks.
- Over-gloving precision work: Excessive bulk or poor fit reduces tactile control, causing operators to mis-handle small parts or lose grip on oily components; machining guidance recommends slim, fine-gauge gloves that feel like part of the hand.
Is glove class the same as glove size?
No. Glove class refers to the protection rating or use category (e.g., ANSI cut resistance A1–A9), while size refers to fit dimensions. A glove can be the correct size but the wrong class for the hazard.
Does a higher ANSI cut class mean it is safer in every machine shop task?
No. Higher cut resistance does not make a glove safe around rotating machinery; safe use depends on the motion hazard, entanglement risk, and whether the glove can be worn without exposure to rotating parts. A high cut class does not mitigate snagging or crush hazards.
What is the key distinction between cut resistance and entanglement safety?
Cut resistance measures how much blade force a glove can withstand (ANSI class), while entanglement safety concerns whether the glove can be caught by moving machine parts. A glove can score highly on cut resistance yet still be extremely dangerous on a running spindle due to snagging.
