What Types of Design Decisions? IBC section 704.11.1 requires that a parapet divider be no less than 30 crawls high OSHA 1926 Subpart M requires a 39-45 inch guardrail or other fall assurance If the outline proficient indicates a 39-45 creep high parapet divider, fall insurance would not be requiredSlide 13
DfCS Examples: Roofs Upper story windows and rooftop parapets SkylightsSlide 14
COURSE OBJECTIVES To give configuration and development experts with aptitudes to distinguish development security dangers To give outline and development experts with abilities to dispose of or lessen the danger of a genuine damage in the configuration stageSlide 15
COURSE OBJECTIVES Safety Engineering-abilities to perceive perils and reveal "shrouded" dangers Design elements to wipe out or diminish the danger of a harm because of a risk OSHA assets for DfCSSlide 16
Crash Course in Safety Engineering Safety Engineering is a claim to fame inside the building field that arrangements with the ID and end of risks. Security Engineering cuts over all building disciplines: Civil, Mechanical, Chemical, Electrical, and additionally numerous branches of science.Slide 17

Worker shocked when his drill rig got excessively near overhead electrical cables. Outline engineer determined groundwater checking wells were to be burrowed straightforwardly under electrical cables. Specialist could have determined wells be burrowed far from electrical cables and/or better educated the business of peril postured by wells\' vicinity to powerlines through the arrangements, details, and offer records.

Hidden Hazards-"Imagine a scenario in which" Analysis A "Consider the possibility that" investigation is an organized conceptualizing techniques for uncovering shrouded dangers Select the limits of the audit and amass an accomplished group Gather data video tapes of operation, configuration reports, upkeep methodology, and so onSlide 37
Hidden Hazards-"Consider the possibility that" Analysis "Consider the possibility that" Situation Questions Failure to take after strategies Procedures are taken after, however are off base Equipment disappointment Utility disappointment Weather Operator not preparedSlide 38
Hidden Hazards-"Imagine a scenario where" Analysis Example Highway Construction Project-What if specialists need to get to channels. Are channels a conceivable restricted space? Shouldn\'t something be said about the electrical cables? Will gear be working close electrical cables? Shouldn\'t something be said about specialist/open harm from car crashes? Do trucks have enough turning space? Is there signage/obstructions to re-direct walkers? Will development vehicles have enough shoulder space to stop on street What if specialist endeavors to physically get channel covers? Is it accurate to say that they are lightweight? Do they have handles?Slide 39
