Spray Nozzle (Pty) ltd, established in 1971, is the manufacturer of the SPRAYDRENCH® range of emergency safety equipment, used for the rapid removal of harmful chemicals and contaminants in the mining, petrochemical, and manufacturing industries, including laboratories and institutions of learning. Spray Nozzle (Pty) ltd is an I.S.O. 9001-2008 compliant company. SPRAYDRENCH® emergency safety equipment is designed and manufactured in South to international safety standards, including ANSI Z 38.1-2008, EN 15154- 1 : 2008, EN 15154-2 : 2006 and DIN 12899-3 : 2008. All equipment is warranted for performance and function, provided it is installed and maintained according to instructions and used for the purposes for which it is intended. Since its original units were designed in 1971, the SPRAYDRENCH® range has been vastly improved and broadened to meet the world's most stringent demands. Exports of the range exceed 40% of production, with sales not only throughout Africa, but also to the Americas, Europe and the Middle East. Customers have a choice of over 120 standard models, fully automated and designed on ACAD, as well as bespoke systems to suit each environment or application. Stainless steel models now form over 90% of the production, with an option of the economical epoxy coated mild steel and Polypropylene variations. The range begins with simple, manually operated units, through platform and platform-assisted models and includes a full range of fully automated units using infra-red diffuse sensors or proximity switches and flow switches. The IP65 automated control panels are becoming increasingly popular, and can be integrated with existing PLC's. Such systems allow for the complete identification, reaction to, and management of all incidents and accidents on the site. Another range of features, which have become popular amongst export clients, are the frost- and heat-protected units, which allow for trouble-free control under severely adverse conditions. Additional to the range, and becoming popular for remote sites, are the fully self- contained units, with header tanks. Each and every model has design-preferred features as well as numerous options available. This comprehensive range allows for an ideal selection from the smallest laboratory units through to the largest self-contained and protected models for hostile site conditions.50
All products are intended to supplement first aidtreatment of injuries and/or contamination, therebymitigating the aggravation to more serious injury. AllSPRAYDRENCH® units should be installed in closeproximity to hazardous areas and must be clearlyidentified as emergency safety showers and/oreyewash stations. They must be free from obstructionand accessible from three directions. In order to ensurecorrect operation of the units, adequate instruction andtraining must be provided to both the maintenance teamas well as the end user. This training should includehow to locate the safety equipment, how to operate thesafety equipment, recognition of safety alarms andbeacons when activated, and how to obtain additionalmedical assistance.In the event of contamination or injury, an industrialnurse and or medical doctor should be contactedimmediately. Only safety equipment which meets withthe OSHA rules and regulations as well as the ANSI Z358.1-2004 and EN norms and safety standards shouldbe installed. In the event of contamination, medicalattention must be sought immediately. Signage must bedisplayed in a prominent area in close proximity to theunit.SPRAYDRENCH® products offer not only corrosion-resistant stainless components on critical items such asvalves and nozzles, but also a range of Polypropyleneunits for certain applications. All units are modular indesign, can easily be upgraded and repaired on site andwithout the use of any special tools. Finally, SprayNozzle has been awarded numerous contracts withblue-chip companies as the sole supplier to their safetyshower and eyewash requirements, making this thenumber one brand in Africa. Spray Nozzle is becominginternationally recognized as a serious contender for allnational and international contracts and applications. 51
