2 Air Traffic Control Towers: Mission Critical Typical Monday Morning Air Traffic Snapshot 2

3 Airline traffic at 10:20 a.m. EDT over the United States Sept. 26, 2014, following a fire at a suburban Chicago ATC Facility 3

4 Consequences of Fire at a Mission Critical Facility: Aurora ATC Facility More than 2,000 flights in and out of Chicago cancelled by evening of fire Flights as far away as Dallas cancelled Ultimate cancellation of 3900 flights in the four days following the fire a Cost to American, United and Southwest estimated in the hundreds of millions of dollars for each airline b $123 million cost in passengers lost economic activity a Some passengers diverted to Detroit a US Travel Association estimate b Boyd Group Int l estimate 4

6 Fire Risk in IT Facilities Fire History Typically involve small fires Potentially large impact Equipment, Data and Business Continuity at Risk Equipment and data loss High cost of downtime Leading cause: electrical distribution equipment Fire Hazard Wires, cables, cord, plugs, outlets Fuel load primarily electronic equipment and power cables: plastics 6

7 Electronic Equipment: Fire Damage Thermal Damage - Due to fire itself (heat) Non-thermal Damage: Combustion Products - Smoke, soot, water, acids Non-thermal Damage: Suppression Agent - e.g., water, foam, dry chemical Electronic equipment is very susceptible to damage from fire 7

8 Electronics: Thermal Damage Component Onset of Damage Storage media (magnetic tape, floppies, etc.) 125 o F (52 o C) Hard drives 150 o F (66 o C) Electronic components 174 o F (79 o C) Paper 350 o F (177 o C) Polystyrene cases, reels 650 o F (310 o C) Microfilm 225 o F (107 o C) Damage results in loss of equipment and data 8

9 Electronics: Non-Thermal Damage from Combustion Products Steam, Smoke, Soot, Various Combustion Products Hydrogen Chloride - From combustion of PVC - Reacts with galvanized zinc components forming ZnCl 2 - ZnCl 2 layer formed, reacts with humidity to produce a corrosive ZnCl 2 solution Corrosive Combustion Gases - HF, HBr, SO 2, CH 3 COOH, NO 2, HCN 9

43 Fire Risk Management 101 Fire risk analysis is a process to characterize the risk associated with fire that addresses the fire scenario or fire scenarios of concern, their probability, and their potential consequences. Risk factors to be considered include life safety and (direct and indirect) economic losses from the loss of function (capacity) or data, loss of professional reputation, and the costs of redundant systems R.W. Bukowski, Fire Protection Engineering Emerging Trends, Issue 76 (09/2013) Risk Considerations for Data /Center Fire Protection 43

44 Fire Risk Management 101 KEY ELEMENTS 1. Risk 2. Scenario 3. Probability 4. Consequences Direct Indirect Mission Critical Facilities: Equipment-related fire Cables, electronic equipment NOT zero Due to fire and extinguishant Ex: Business interruption 44

45 Fire Risk Management Standards & Guides SFPE Engineering Guide: Fire Risk Assessment (SFPE G ) NFPA 551 Guide for the Evaluation of Fire Risk Assessments NFPA Handbook of Fire Protection, Chapter 8, Section 3, Fire Risk Analysis ASTM E a Standard Guide for Development of Fire-Hazard-Assessment Standards 45

46 Mission Critical Facility Fire Protection Sprinkler and Clean Agent systems vastly different Design objectives different: Control vs Extinguishment Preaction systems best suited to protection of structure Clean agent systems best suited to protection of contents of structure Sprinkler systems alone inappropriate for protection of high value assets Clean agents not ideally suited for structural protection Loss during a fire NOT limited to fire damage Potential loss differs for clean agent vs sprinkler systems 46

47 Quantifying Loss: Direct vs. Indirect Costs of Fire Losses and costs associated with a fire are not limited to the equipment involved in the fire Direct: Equipment involved in the fire Data Historical and Intellectual Property Financial records Cost of Clean up Indirect: Business interruption & downtime Insurance Lawsuits Collateral Damage Loss of customer confidence 47

48 Shaw Datacenter Fire: Minimum Fire Protection and Its Consequences The potential consequences of adopting a minimum protection approach to fire protection can be clearly seen in the results of the recent Shaw datacenter outage in Calgary 48

49 Shaw Datacenter Fire: Transformer fire sets off sprinkler system Sprinklers take out backup systems housed on site Knockout out of primary and backup systems supporting key public services Crippled city services, including 311 services Delay of 100s of surgeries at local hospitals IBM Canada forced to fly backup tapes holding vehicle and property registration data to a backup facility in Markham, Ontario 49

50 Shaw Datacenter Fire: Extensive water damage to furniture, walls and sensitive electronic equipment on the floors below the top story fire location Temporary relocation of over 900 Shaw employees while damage is repaired Six days of service outage 50

51 Shaw Datacenter Fire: More than 20,000 Shaw business and household clients watched their cable, telephone and Internet services disappear almost immediately City and provincial clients watched their own networks go dark as the water trickled down, affecting other data companies below the fire. Some cellular carriers were also said to be affected, as well as ATB banking services, ATMs and debit terminals throughout the city 51

52 Shaw Datacenter Fire: Competitor Q9 Networks Inc., which operates three data centres in the city, has early detection systems that can detect smoke and use gases that don t harm people to prevent fires from starting. Water needs to be there by law, said Q9 chief executive Osama Arafat, but you want to try and deal with a fire using less destructive means first. Source: 52

53 Case Study: Iowa State Legislature Building Datacenter Fire: February 18, 2014 Mission Critical Facility Payroll processing for state employees was scheduled for that evening Dept of Revenue needed to process tax collections. Justice Dept needed to process claims and fee payments. 53

54 Iowa Legislature Fire Timeline 3pm Fire ignites: FM-200 System deploys 9pm Data Center Cleared of burnt equipment 2am Major websites and agency systems restored 3am Remaining major agency applications restored 54

55 Fire Protection for Mission Critical Facilities Fires DO Occur in Mission Critical Facilities Risk, Consequences, Losses dependent on facility & fire protection system Sprinklers : fire control/structure protection Clean agents: fire extinguishment/content protection Substantial risk reduction at very high benefit/cost ratios may be realized by protecting sensitive, valuable and mission-critical assets, such as those found in IT and telco facilities, with both a clean agent system and a sprinkler system. 55
