Key to this is the proper selection and use of hanger rods, as specified in 𝐍𝐅𝐏𝐀-𝟏𝟑. 🔧𝐇𝐚𝐧𝐠𝐞𝐫 𝐑𝐨𝐝 𝐑𝐞𝐪𝐮𝐢𝐫𝐞𝐦𝐞𝐧𝐭𝐬: ⓵ 𝐒𝐭𝐚𝐧𝐝𝐚𝐫𝐝 𝐒𝐢𝐳𝐞 𝐂𝐨𝐦𝐩𝐥𝐢𝐚𝐧𝐜𝐞: Hanger rod sizes must match the sizes approved for the hanger assembly and must not be smaller than the dimensions in given Table. ⓶ 𝐄𝐱𝐜𝐞𝐩𝐭𝐢𝐨𝐧𝐬 𝐟𝐨𝐫 𝐒𝐦𝐚𝐥𝐥𝐞𝐫 𝐑𝐨𝐝𝐬: Smaller diameter rods can be used if the hanger assembly has been tested and listed by a recognized testing laboratory and installed within the specified pipe size limits. 💡 𝐊𝐞𝐲 𝐏𝐨𝐢𝐧𝐭𝐬 𝐭𝐨 𝐂𝐨𝐧𝐬𝐢𝐝𝐞𝐫: ⓵ Always refer to attached given table for the minimum rod size requirements. ⓶ Ensure that any deviations with smaller rods are backed by proper testing and listings. ⓷ Proper installation within the specified limits is crucial for system integrity and compliance. By adhering to these guidelines, we maintain the structural integrity and effectiveness of fire protection systems, ensuring they function as intended during critical moments. 🚒 #MechanicalEngineering #FireProtection #NFPA13 #SafetyStandards

Understanding the contrast between a Proprietary System and a Prescribed System is crucial when it comes to fall-arrest or access assemblies like static lines, rigid rails, or davits. These systems can be categorised based on their design and installation approach. Proprietary System (Engineered System): •Pre-engineered and compliant with the applicable Australian Standard if installed within the manufacturer's installation limitations and guidelines. •Site-specific limitations are to be considered and documented as necessary. •Manufacturer documentation supplied as part of the handover documentation for the installation. Prescribed System (Mixed Manufacturer System): •Each system is individually designed by a rigger or engineer. •The installer must provide relevant supporting documentation and calculations to validate the design, ensuring compliance with Australian Standards. •Prepared by the installer considering the engineering, materials, site-specific usage requirements. Knowing the distinction between these systems is essential for various reasons, including ensuring engineering compliance and adherence to safety standards. #HeightSafety #FallPrevention #EngineeringSafety #Kerrectgroup #heightspecialists

There has been much posted about the new regulations affecting Tower Cranes in Ontario as of Jan 1, 2024. I would encourage you to review the memo that was released late December regarding the MOL enforcement direction as a result of those changes. Key point: "If MLITSD inspectors encounter a tower crane that has not been inspected by mechanical, hydraulic and/or electrical engineers due to the identified challenges finding the necessary engineering expertise, we will inform the workplace parties of the new requirements that came into force as of January 1st, 2024, and that as of June 1, 2024 the MLITSD will enforce section 158 in its entirety. Inspectors will record this in the narrative portion of the field visit. All other structural inspections and verifications as they are currently performed are expected to be done as of January 1, 2024 Enforcement of all other amended sections coming into force on January 1, 2024 will commence as of that date." #prevention #construction #towercranes #regulations #enforcement #safety #ontario #engineer

Lift Specialist: It isn't a mere title like many will think, it's born from a place of knowledge, skill and expertise in structural, mechanical, transportation and installation engineering. Which focuses on couple of core deliverable: Lift engineering Lift management Lift transportation Lift regulations Lift best practices Applicable rigging among others.....

Failure is central to Engineering Every single calculation that an engineer makes is a failure calculation. Successful engineering is all about understanding how things break or fail . #Engineering #fitter #machinist #hardwork #pressurevessel #assemblies #maintenance

“Is this a crane and does it need an annual structural inspection?” This question has come up a few times recently. The answer is YES, They fall under CSA Z150-20. A structural inspection is only part of the annual requirement. These small spider cranes require an annual mechanical inspection as well before the engineer can stamp the final certificate. These small cranes have the same requirements as a large mobile crane, they are required to have a log book, which needs to be filled out prior to daily use. Quite often it is found that these logs are missing or have not been completed. This makes it difficult for the inspector to review and verify if there have been issues noted and corrected or not .

A measuring tape is one of the most indispensable pieces of equipment for construction professionals. No matter what role you play on the job site, you always need to have an engineers tape measure ready so that you can confidently assess the work being done. #newprojects #constructionlife #civilengineering
