Whilst Sodium Hypochlorite is a an excellent disinfectant it is highly corrosive. Wikipedia lists Sodium hypochlorite as a strong oxidizer. Oxidation reactions are corrosive. Solutions burn the skin and cause eye damage, especially when used in concentrated forms.
Global Harmonized System (GHS) classification of sodium hypochlorite solution: Skin corrosion/irritation (Sub-category 1B)
Serious eye damage/eye irritation (Category 1)
Acute aquatic toxicity (Category 1) Chronic aquatic toxicity (Category 1)
Source: Western University, Canada
Inhalation of gases released from hypochlorite solutions may cause eye and nasal irritation, sore throat, and coughing at low concentrations. Inhalation of higher concentrations can lead to respiratory distress with airway constriction and accumulation of fluid in the lungs (pulmonary edema).

Usage of Sodium Hypochlorite is recommended for well ventilated spaces and outdoors. Office Interiors that are airconditioned should not be sprayed with Sodium hypochlorite. It will over time destroy furniture, furnishings and create health problems for people being exposed.
