Abstract Biodeterioration on concrete surfaces of vertical elements of bridges represents a serious challenge to the highway infrastructure in Louisiana. This report aims to document the causes of biodeterioration of concrete surfaces and to document current conventional and state-of-the-art practices implemented to prevent and clean biofilm. A comprehensive literature review of previous research has been carried out in order to determine the cause and mechanisms of the biodeterioration as well as to identify current methods that state DOTs have implemented in order to maintain their bridges and allow them to function in optimal structural and performance conditions. -

Safety Guidelines for Operating High Pressure Washer Equipment
Employee Name Date Company Name Date Safety Guidelines for Operating High Pressure Washer Equipment It’s imperative that all operators read the safety and operating instructions before using any Power Line Industries, Inc. product. Pressure Washing can be dangerous if proper procedures are not followed and appropriate safety gear is not utilized. Read the engine owner’s manual for instruction and safety precautions on engine operation. This safety guideline must be reviewed and signed by all operators prior to running any high pressure washer equipment. p PRESSURE WASHER SAFETY Pressure Washing is a serious business that can result in serious injury or death when proper safety precautions are not followed. Awareness of common jetting hazards, knowing how to protect oneself from them, and learning and practicing the proper safety procedures can greatly reduce the chances of disaster striking at unexpected moments. p COMMON PRESSURE WASHING HAZARDS When water is pressurized to 4,000 PSI, it becomes a potentially deadly force that can easily result in serious injury when the water jet comes into contact with skin or eyes. The impact of a high pressure nozzle, leaky hose or being hit by wash debris (rocks, etc.) can cause potentially life threatening injuries. When washing is performed in confined spaces other OSHA rules for confined space entry and personal protective equipment must be followed. p PERSONAL PROTECTION Proper dress is also important when performing high-pressure water power washing. Coveralls should be worn. A heavy duty raincoat should also be worn to keep technicians dry and to help provide a barrier in the event there is contact with flying debris from washing. -

All information is anonymised or sanitised, as appropriate. 1 Rigging failure - clump weight dropped to seabed What happened? A clump weight used for anchoring a weather buoy was being deployed over the sea when the long link chain attached to the vessel crane hook failed resulting in the clump weight dropping to the seabed. The 2.6t clump weight was the anchor component of a mooring arrangement for the weather buoy. The load was rigged using a supplied mooring arrangement, which followed the manufacturer’s drawing in the weather buoy manual. Instead of a 450kg weight it was decided to use the 2.6 tonne clump weight already available and which had been shipped to the location for deployment. A service specialist prepared a deployment procedure which was discussed with those involved in the task. Shortly after the load was submerged in the sea the chain link attached to the quick-release mechanism snapped, and the load dropped to the seabed in an uncontrolled manner. Clump weight and the long link chain used Chain link snapped on the quick Applicable Life Saving for lifting release mechanism while deployed Rule: Safe Mechanical over the sea Lifting The findings revealed: • The rigging failed because a larger clump weight (2.6t) was selected than the design allowed for (450kg). -
Voluntary Guidelines to Prevent the Spread of Aquatic Invasive
VOLUNTARY GUIDELINES TO PREVENT THE INTRODUCTION AND SPREAD OF AQUATIC INVASIVE SPECIES: RECREATIONAL ACTIVITIES Aquatic Nuisance Species Task Force November 2013 In July 2011, the Aquatic Nuisance Species Task Force (ANSTF) re-established the Recreational Guidelines Committee (Committee) composed of 55 Federal and State agency, non-profit and industry representatives. The Committee’s mission is to update the 2000 ANSTF Recommended Voluntary Guidelines for Preventing the Spread of Aquatic Nuisance Species Associated with Recreational Activities (Federal Register/ Vol. 65, No. 76/ Thursday, April 13, 2000/ Notices, Pg. 19953). Those guidelines were revised taking into account new aquatic invasive species (AIS), and new recreational activities and equipment. Guidelines were revised for six recreational activities: anglers, motor boaters, non-motorized boaters, scuba divers and snorkelers, seaplane pilots, and waterfowl hunters. The purpose of these guidelines is to: • Provide a consistent, practical, and effective document to inform outreach efforts geared toward public recreationalists to prevent the spread of AIS, • Take into account the specific pathways, vectors, and life histories of all AIS, including fish, aquatic plants, invertebrates, and pathogens, and • Promote voluntary actions to support the national Stop Aquatic Hitchhikers!™ campaign, as well as statewide efforts such as Clean Boats, Clean Waters. Stop Aquatic Hitchhikers!TM is a national education campaign that helps recreational users to become part of the solution to stop the spread of AIS. Launched in 2002, the campaign was created under the auspices of the ANSTF. Joining the campaign is free and easy. Visit www.protectyourwaters.net and then click on “Become a Partner”. As of 2013, over 1,100 entities including agencies (federal, state, tribal, county), universities, colleges, schools, businesses, industries, non-profit organizations, and clubs have joined helping to reach millions of recreational users. -
