Unformatted text preview: ENGR201 PROFESSIONAL PRACTICE AND RESPONSIBILITY ... WILL BEGIN HERE AT 16:15 WELCOME TO ALL STUDENTS FACULTY OF ENGINEERING AND COMPUTER SCIENCE 1 CHAPTER 3 • SAFE WORK PRACTICES General safety concepts Accidents Prevention FACULTY OF ENGINEERING AND COMPUTER SCIENCE 2 1 Related upcoming lectures • Ch 7 : Code of Ethics : duties and Ch. obligations towards the public • Ch. 11 : Occupational health and safety issues for engineering p j projects : Q Quebec and Canadian legislation • Ch. 12 : Liability FACULTY OF ENGINEERING AND COMPUTER SCIENCE 3 TOPIC 1 : General safety concepts •Occupational hazards : risk p factors •A simple tool : the Risk Index •At the University : what is the same, what is different FACULTY OF ENGINEERING AND COMPUTER SCIENCE 4 2 Risk factors • “Each of the elements of a system Each which contributes to an increase in the probability of an event, change or failure in that system, thereby making it less reliable” FACULTY OF ENGINEERING AND COMPUTER SCIENCE 5 Risk factors INDIVIDUAL ABILITY TRAINING AND EDUCATION BEHAVIOUR WORK ORGANIZATION TASK DEFINITION AND EXECUTION EQUIPMENT COMMUNICATION O.H.S. STANDARD AND REGULATION INTERACTION WITH NEARBY MATTER OR ACTIVITY SUPERVISION AND CONTROL HAZARDOUS MATERIAL PHYSICAL ENVIRONMENT FACULTY OF ENGINEERING AND COMPUTER SCIENCE 6 3 A simple tool : the Risk index (R.I.) • • • • A simple, quick indicator simple Useful to establish priorities R.I. = C x E x P where : • C = Consequence (most likely result) • E = Exposure (presence of the danger) • P = Probability (events lead to accident) FACULTY OF ENGINEERING AND COMPUTER SCIENCE 7 C = consequence • • • • • • Catastrophic / multiple deaths Death Total permanent incapacity Partial permanent incapacity Total temporary incapacity Medical intervention FACULTY OF ENGINEERING AND COMPUTER SCIENCE 100 75 50 25 10 1 8 4 E = exposure • • • • • All the time / several times a day Often / daily Usually / weekly to monthly Occasionally / monthly to yearly Rarely 10 6 3 2 1 FACULTY OF ENGINEERING AND COMPUTER SCIENCE 9 P = probability (not mathematical) • • • • • • Very likely 50/50 chance Unusual Exceptional Unbelievable Nearly impossible FACULTY OF ENGINEERING AND COMPUTER SCIENCE 10 6 3 1 05 0,5 0,1 10 5 Risk index = C x E x P • Result : 0 1 to 10 000 0,1 • Use : to establish priorities • Above 3000 : act now, it is very urgent • Between 1000 and 3000 : intervene quickly y • Below 1000 : treat each case individually FACULTY OF ENGINEERING AND COMPUTER SCIENCE 11 Risk index : an exemple • A compressed gas bottle falls falls... • on somebody’s foot • on something solid and its valve is broken off • Two possible outcomes are identified : • a foot is broken • the bottle shoots away like a rocket… FACULTY OF ENGINEERING AND COMPUTER SCIENCE 12 6 Risk index = C x E x P • Foot hurt : R.I. = 10 x 10 x 4 = 400 RI • Rocket away : R.I. = 75 x 10 x 4 = 3000 • Total : 3400 immediate action required : tie the bottle, bottle put its cap on Other possibilities ? The gas is toxic / flammable, the bottle falls down, etc. FACULTY OF ENGINEERING AND COMPUTER SCIENCE 13 At the University : what is the same • Standard risks associated with buildings, chemicals, machines, etc. • The same laws and regulations apply FACULTY OF ENGINEERING AND COMPUTER SCIENCE 14 7 At the University : what is different • No “production” involved production • Experimental situations • Untrained and changing “workers” : the students • Multiple processes occur at the same time : teaching, working, learning... FACULTY OF ENGINEERING AND COMPUTER SCIENCE 15 TOPIC 2 : Accidents FACULTY OF ENGINEERING AND COMPUTER SCIENCE 16 8 Definition : Industrial accident •“industrial accident” means a sudden and unforeseen event, attributable to any cause, which happens to a person, arising out of or in the course of his work and resulting in an employment injury to him; FACULTY OF ENGINEERING AND COMPUTER SCIENCE 17 Definition : Occupational disease • “occupational disease” means a disease occupational disease contracted out of or in the course of work and characteristic of that work or directly related to the risks peculiar to that work (from An Act respecting industrial (f accidents and occupational diseases R.S.Q., chapter A-3.001) FACULTY OF ENGINEERING AND COMPUTER SCIENCE 18 9 Why accidents happen • “HOW”, “WHEN”, “WHERE” and HOW WHEN WHERE “WHAT” are usually easy to find • Many possible answers to “WHY”, depending on perspective FACULTY OF ENGINEERING AND COMPUTER SCIENCE 19 WHY ???? Accident causation (CCOHS) FACULTY OF ENGINEERING AND COMPUTER SCIENCE 20 10 Exemple 1 :amputation of a thumb in a plastic extruder • The operation : production of plastic "slugs" by an extrusion process FACULTY OF ENGINEERING AND COMPUTER SCIENCE 21 Exemple :amputation of a thumb in a plastic extruder • Brand new machine : unfamiliar • Untrained worker • Ordered/sold/installed without "safety barriers, painted yellow" • Incomplete/Missing instructions manual • Language FACULTY OF ENGINEERING AND COMPUTER SCIENCE 22 11 Exemple 2 : fork lift operator crushed to death • The operation : loading pallets into truck FACULTY OF ENGINEERING AND COMPUTER SCIENCE 23 Example : fork lift operator crushed to death • Truck leaves without warning as fork lift enters trailer • Sudden fall between dock and trailer • No coordination • No safety system FACULTY OF ENGINEERING AND COMPUTER SCIENCE 24 12 Exemple 3 : firemen killed by burning church collapse • May 25, 1987 : Unitarian Church on 25 Sherbrooke St. W. burns down • Old (early 1900s), unusual design • Criminal activity • Material (cast iron columns) failure under intense heat • Firemen in wrong place at wrong time FACULTY OF ENGINEERING AND COMPUTER SCIENCE 25 Accident analysis • To prevent reoccurrence of ... • • • • • • Aircraft crashes Nuclear or chemical disasters Common mode failures Fires Falls "Ordinary" accidents … FACULTY OF ENGINEERING AND COMPUTER SCIENCE 26 13 TOPIC 3: Prevention •The ultimate goal : the elimination, g , at the source, of dangers to the health, safety and physical well-being of workers. (An Act respecting occupational health and safety R S Q chapter S R.S.Q., S2.1) FACULTY OF ENGINEERING AND COMPUTER SCIENCE 27 Three main means of intervention FACULTY OF ENGINEERING AND COMPUTER SCIENCE 28 14 1 Planning and organization • Health and safety program responsibilities at the operational level • Health and safety procedures FACULTY OF ENGINEERING AND COMPUTER SCIENCE 29 2 Practical means • Safety standards • Collective protection equipment • Individual protection equipment FACULTY OF ENGINEERING AND COMPUTER SCIENCE 30 15 3 Training and information • • • • • Posted safety warnings Procedures Operating manuals Supervision WHMIS (Workplace Hazardous Materials Information System) FACULTY OF ENGINEERING AND COMPUTER SCIENCE 31 AT CONCORDIA UNIVERSITY • Environmental Health and Safety Office • http://ehs.concordia.ca/index.php • • • • • Policies, programmes, procedures Manuals g Training Emergency response Resources FACULTY OF ENGINEERING AND COMPUTER SCIENCE 32 16 CONCLUSION • Health and safety = paramount concern for engineers • Ideally, dangers would be eliminated at source • Many accidents could be avoided : simple, costeffective prevention • Realistically, decisive risk factors must be identified and controlled • When "things happen", consequences must be g pp , q minimized and measures taken to prevent a reoccurrence • Accident / incident = source of info »»» investigate FACULTY OF ENGINEERING AND COMPUTER SCIENCE 33 REQUIRED READING • Concordia University - Laboratory Safety Manual http://ehs.concordia.ca/hm/labsafety.ht ml look for the "Laboratory Safety Manual" under Hazardous Materials > Lab Safety d H d M t i l L bS f t FACULTY OF ENGINEERING AND COMPUTER SCIENCE 34 17 SUGGESTED READING • Concordia University - Office Ergonomics Manual and SelfAssessment Checklist • http://ehs.concordia.ca/ih/ergo.html • look for the "Office Ergonomics Manual" and the checklist under Ergonomics FACULTY OF ENGINEERING AND COMPUTER SCIENCE 35 THAT'S IT FOR THIS WEEK !
