Proposed changes which impact the same subject have been grouped to permit consideration in consecutive changes. Proposed change numbers that are indented are those which are being heard out of numerical order. Indentation does not necessarily indicate that one change is related to another. Proposed changes may be grouped for purposes of discussion at the hearing at the discretion of the chair. Note that some M code change proposals may not be included on this list, as they are being heard by another committee.

The timeweightedtime-weighted average (TWA) concentration for a normal eighthoureight-hour workday and a 40-hour workweek to which nearly all workers can be repeatedly exposed without adverse effect, based on the OSHA PEL, ACGIH TLV-TWA, AIHA TERA OARS WEEL, or consistent value. Reason: The WEEL values were previously issued by the American Industrial Hygiene Association. These values are now issued by the Toxicology Excellence for Risk Assessment (TERA) Occupational Alliance for Risk Science (OARS). Please visit this website to view the WEEL database: http://www.tera.org/OARS/WEEL.html This change is consistent with addendum d to ASHRAE Standard 34-2013 which can be found here: https://www.ashrae.org/standards-research-- technology/standards-addenda Bibliography: http://www.tera.org/OARS/WEEL.html https://www.ashrae.org/standards-research--technology/standards-addenda Cost Impact: Will not increase the cost of construction This proposal simply updates a definition to indicate what organization is responsible for WEEL values, which has no impact on construction cost. M 1-15 : 202-OCCUPATIONAL EXPOSURE LIMIT (OEL)- FERGUSON4853 ICC COMMITTEE ACTION HEARINGS ::: April, 2015 M4 M 2-15 202 Proponent: Janine Snyder, representing Plumbing, Mechanical, and Fuel Gas Code Action Committee ([email protected]) 2015 International Mechanical Code Revise as follows: SECTION 202 DEFINITIONS ACCESS (TO). That which enables a device, appliance or equipment to be reached by ready access or by a means that first requires the removal or movement of a panel, door or similar obstruction [see also "Ready access (to)"]. READY ACCESS (TO). That which enables a device, appliance or equipment to be directly reached, without requiring the removal or movement of any panel, door or similar obstruction [see "Access (to)"]. Reason: The term "door" has caused confusion because one must pass through one or more egress doors before reaching any object inside of a building. For example, if an emergency control must be readily accessed, personnel would likely pass through one or more egress/ingress doors before reaching the emergency control, and that is the reality of the situation. The term "door" as used in the definitions was referring to "access doors" similar to panels. The term "access door" might be an alternative to the term "door" because "access door" clearly differentiates between access doors/panels and egress doors. This proposal intends to distinguish egress doors from cabinet doors, access doors and alcove doors and intends to prevent these definitions from being misinterpreted as prohibiting room and closet doors. Cost Impact: Will not increase the cost of construction This proposal will not increase the cost of construction because no additional labor, materials, equipment, appliances or devices are mandated beyond what is currently required by the code nor are the code requirements made more stringent. M 2-15 : 202-ACCESS (TO)- SNYDER3614 ICC COMMITTEE ACTION HEARINGS ::: April, 2015 M5 M 3-15 202 Proponent: Janine Snyder, representing Plumbing, Mechanical, and Fuel Gas Code Action Committee ([email protected]) 2015 International Mechanical Code Revise as follows: SECTION 202 DEFINITIONS COMMERCIAL COOKING APPLIANCES. Appliances used in a commercial food service establishment for heating or cooking food and which produce grease vapors, steam, fumes, smoke or odors that are required to be removed through a local exhaust ventilation system. Such appliances include deep fat fryers; upright broilers; griddles; broilers; steam-jacketed kettles; hot-top ranges; under-fired broilers (charbroilers); ovens; barbecues; rotisseries; and similar appliances. For the purpose of this definition, a commercial food service establishment shall include any buildingis where food is prepared for sale or is prepared on a portion thereof used for the preparationscale that is by volume and servingfrequency not representative of fooddomestic household cooking. Reason: 1) The current definition is circular in that Chapter 5 uses the term and dictates where a hood is required for such appliances, yet this definition says that a commercial cooking appliance is something that requires a hood (local exhaust system). The current definition is flawed because if Chapter 5 does not require a hood for a particular cooking appliance, then this definition would say that it is no longer a commercial cooking appliance.
