OWR COBRA Miniature Spray Decontamination Unit

Overview

The OWR COBRA Miniature Spray Decontamination Unit is a compact, manually operated decontamination device engineered for rapid, targeted chemical decontamination of skin, personal protective equipment (PPE), and small surface areas in field or laboratory emergency response scenarios. Unlike automated bottle washers or benchtop cleaning systems, the COBRA operates on a positive-pressure spray principle—leveraging human-applied mechanical force via an integrated ergonomic hand pump to generate consistent, controllable mist or stream delivery from its integrated 0.5 L reservoir. Its design adheres to the functional requirements of first-response decontamination protocols where portability, immediate deployability, and operator independence from external power or compressed gas sources are critical. The unit is not intended for routine glassware washing or high-throughput labware processing; rather, it serves as a Class I personal decontamination tool aligned with ISO 15883-1 (reprocessing of medical devices) and EN 14885 (chemical disinfectant efficacy testing) application contexts requiring manual, low-volume agent delivery.

Key Features

• Compact form factor (25 cm height × 7.3 cm diameter) enables belt-mounting, backpack integration, or rapid deployment from emergency kits.
• Manually actuated stainless-steel hand pump delivers repeatable pressure output without reliance on electricity, batteries, or external air supply—ensuring operability in off-grid, hazardous, or power-failed environments.
• Chemically resistant construction: 316 stainless steel pump housing, UV-stabilized polypropylene reservoir, and fluorocarbon-lined elastomeric seals ensure compatibility with common disinfectants including hypochlorite solutions, hydrogen peroxide (≤6%), quaternary ammonium compounds, and alcohol-based formulations.
• Adjustable nozzle assembly supports both fine-mist and focused-stream discharge modes—optimized for ocular/dermal rinse (per ANSI Z358.1–2022 flow rate guidance) or localized surface decon.
• Integrated 100 cm reinforced PVC hose with swivel coupling minimizes kinking and enables ergonomic positioning during use.
• Includes certified shoulder strap (EN 13595-compliant webbing), nylon-bristle cleaning brush for PPE texture surfaces, and calibrated filling funnel to prevent overfilling and ensure accurate dosing.

Sample Compatibility & Compliance

The COBRA is validated for use with liquid disinfectants meeting EPA List N, WHO-recommended formulations, or EU Biocidal Products Regulation (BPR) Annex VI criteria. It is not compatible with viscous suspensions, foaming agents requiring metered air induction, or oxidizers exceeding material compatibility thresholds (e.g., >12% sodium hypochlorite). Device construction complies with RoHS 2011/65/EU and REACH SVHC screening standards. While not a medical device under MDR 2017/745, its operational parameters align with IEC 61000-6-2 (immunity) and IEC 61000-6-3 (emission) for non-electrical equipment used in mixed-use environments. Documentation includes full material traceability (mill test reports for SS316), chemical resistance validation data per ASTM D543, and third-party verification of burst pressure rating (≥8 bar static).

Software & Data Management

The COBRA is a fully mechanical, analog device with no embedded electronics, firmware, or digital interface. Consequently, it requires no software installation, network connectivity, or cybersecurity controls. All operational records—including usage logs, refill timestamps, and maintenance inspections—are maintained manually per GLP-compliant laboratory notebooks or institutional incident reporting systems. This architecture eliminates risks associated with electronic failure, data corruption, or regulatory noncompliance under FDA 21 CFR Part 11, making it suitable for audit-trail-light environments such as field laboratories, mobile response units, or ISO/IEC 17025-accredited facilities where procedural simplicity and deterministic repeatability are prioritized over digital traceability.

Applications

• Rapid dermal/ocular decontamination following accidental chemical splash exposure (e.g., acids, alkalis, solvents) in synthetic chemistry labs, pharmaceutical QC suites, or battery R&D facilities.
• On-the-spot decon of respirator valves, face shield interiors, and glove cuffs prior to doffing in biosafety level 2 (BSL-2) containment zones.
• Targeted surface decontamination of handheld instruments (pipettes, spectrophotometer cuvette holders, pH probe housings) between users in shared core facilities.
• Field-deployed decon support for environmental sampling teams handling contaminated soil/water matrices in accordance with ASTM D5697 and EPA Method 8270D chain-of-custody protocols.
• Training module for emergency response drills—enabling realistic simulation of time-critical decon actions without consumable waste or facility infrastructure dependency.

FAQ

Is the COBRA compliant with ANSI Z358.1 for emergency eyewash use?
No—it delivers <1.5 L/min at 30 psi, falling below the 1.5 L/min minimum flow requirement for plumbed eyewash stations. It is classified as a supplemental personal rinse device, not a primary emergency eyewash.
Can the COBRA be sterilized in an autoclave?
No. The elastomeric seals and plastic components are not autoclave-rated. Sterilization is limited to chemical immersion (e.g., 70% ethanol, 0.5% glutaraldehyde) per manufacturer’s compatibility chart.
What is the service life of the pump mechanism?
Rated for ≥50,000 actuation cycles under nominal load (0.5 L fill, 4–6 bar operating pressure), verified via accelerated wear testing per DIN 50109.
Does OWR provide calibration documentation?
Yes—each unit ships with a Certificate of Conformance (CoC) referencing EN ISO 9001:2015 manufacturing controls and batch-specific material certifications. No periodic recalibration is required due to mechanical-only operation.
Is the shoulder strap CE-marked for personal protective use?
The strap meets EN 13595-1:2002 mechanical strength requirements but is not certified as PPE under Regulation (EU) 2016/425—its role is ergonomic support, not impact or cut protection.
