| Plumbed Eyewash | Laboratories, chemical processing areas, manufacturing sites, and facilities with a reliable water supply. | Fixed to a potable-water line and installed in an accessible location near the hazard. | 0.4 gal/min (1.5 L/min) for at least 15 minutes under ANSI/ISEA Z358.1 guidance. | Continuous water supply; water should be clean and delivered at a tepid temperature. | Ready for repeated use, low replenishment workload, and suitable for frequent chemical-handling operations. | Requires plumbing, drainage planning, freeze protection where necessary, and regular flushing. | Check pipe connections, local plumbing rules, water pressure, and metric or imperial fittings. |
| Self-Contained Eyewash | Remote work areas, temporary projects, leased buildings, and locations without permanent plumbing. | Wall-mounted, floor-mounted, or placed on a stable support near the hazard. | Designed to provide the required eyewash flow for at least 15 minutes; verify the product’s tested performance. | Reservoir-based system using potable-quality fluid or a manufacturer-approved preservative solution. | Flexible installation, rapid deployment, and no permanent water connection. | Limited capacity, scheduled cleaning and refilling, solution replacement, and temperature control requirements. | Confirm tank volume, refill availability, service interval, operating-temperature range, and transport restrictions. |
| Eye/Face Wash Station | Workplaces where splashes may affect both the eyes and surrounding facial area, including chemical and battery-handling zones. | Usually plumbed or self-contained; dual outlets should direct a broad, gentle stream to both eyes and the face. | 3.0 gal/min (11.4 L/min) for at least 15 minutes under ANSI/ISEA Z358.1 guidance. | Continuous or stored supply, depending on configuration; water or solution must be clean and tepid. | Provides a larger coverage area than a basic eyewash and supports simultaneous flushing of the eyes and face. | Uses more water and may require more space, drainage capacity, and higher supply flow. | Verify spray-pattern testing, basin size, inlet requirements, and compatibility with regional water systems. |
| Combination Shower and Eyewash | Chemical plants, metal finishing, laboratories, refineries, battery rooms, and areas with full-body splash risk. | Floor-mounted unit connected to a water line; the eyewash and shower must be usable at the same time. | Shower: 20 gal/min (75.7 L/min); eyewash: 0.4 gal/min, or eye/face wash: 3.0 gal/min, for at least 15 minutes. | Continuous potable-water supply with sufficient flow and pressure for simultaneous operation. | One centralized unit addresses eye, face, and full-body contamination emergencies. | Highest space, water, drainage, and installation requirements; may need freeze protection and privacy considerations. | Assess water capacity, drainage, floor loading, local safety codes, and access clearance before purchase. |
| Drench Shower | Areas with a significant risk of corrosive, toxic, or irritating substances contacting clothing or the body. | Floor-mounted or ceiling-mounted, positioned along an unobstructed emergency route close to the hazard. | 20 gal/min (75.7 L/min) for at least 15 minutes under ANSI/ISEA Z358.1 guidance. | Continuous clean-water supply; the system must maintain the required flow without harmful pressure. | Rapidly flushes large areas of the body and contaminated clothing after a major splash. | Does not independently provide focused eye flushing; requires substantial water flow and drainage. | Confirm pull-rod height, spray coverage, drainage design, insulation, and protection against accidental activation. |
| Portable Pressurized Eyewash | Construction sites, maintenance work, mobile laboratories, utility projects, and short-term operations. | Portable tank placed or secured near the work area; no fixed plumbing is needed. | Performance depends on the tested model; it should provide the required emergency flushing flow for the stated duration. | Pressurized reservoir filled with clean water or an approved flushing solution. | Mobile, quick to deploy, and useful where work locations change frequently. | Requires pressure checks, refilling, cleaning, and protection from damage or excessive heat and cold. | Review tank capacity, pressure gauge, refill procedure, lifting weight, and local transport requirements. |
| Personal Eyewash Bottle | Individual workers, vehicles, laboratories, and locations requiring immediate supplementary first aid. | Stored within immediate reach of the task or carried by a worker when appropriate. | Flow and duration vary by bottle; a bottle is generally a supplementary measure, not a substitute for a compliant station. | Sealed, sterile, or preserved solution in a limited-volume container; expiration dates must be monitored. | Very portable, simple to use, and capable of providing immediate initial flushing while the user reaches a station. | Limited volume and coverage; bottles may not provide the continuous flow or 15-minute duration expected from a full station. | Check shelf life, tamper seals, storage temperature, replacement policy, and compatibility with the workplace hazard assessment. |
